Intent not going to the correct activity

I am trying to write a game as an app. I have one screen which is just three buttons, Edit, Play and Exit. When I click on the Edit button, it goes to PlayTheGame, and not to the correct activity (EditWords). The same thing happens when I click on the Exit button, and it goes to the PlayTheGame activity and not exiting the app.
What am I doing wrong, and how do I fix my code so that the buttons go to the correct activities?
Thank you in advance for any and all help you can provide me.
Here is the code
l = (Button) findViewById(R.id.edit);
l.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i1 = new Intent(theGame.this, EditWords.class);
startActivity(i1);
}
});
x = (Button) findViewById(R.id.ptg);
x.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i2 = new Intent(theGame.this, PlayTheGame.class);
startActivity(i2);
}
});
e = (Button) findViewById(R.id.exit);
e.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
finish();
System.exit(0);
}
});

Uninstall apk -> Clean the project -> try to build again.
Also if you want to exit the entire app use, finish() and finishAffinity()

Convert Edittext to readonly and Make it editable on Button Press

i got this nw. Before clicking on the button, my EditText is just viewable:
After button press, it should convert to an editable field:
I want the EditText field line to disappear and become read only and on button click make it editable. But this just fades the line and also the text inside it loses it visual appearance.
Here's my code:
et1.setEnabled(false);
et1.setFocusable(true);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
et1.setEnabled(true);
et1.requestFocus();
}
});

Your XML should look like this,
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="vertical">
<EditText
android:id="#+id/et1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ems="10"
android:inputType="textPersonName"
android:text="Name" />
<TextView
android:id="#+id/tv1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView" />
<Button
android:id="#+id/btn1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
</LinearLayout>
Now, add the following code to your activity class.
//init the views.
et1.setVisiblity(GONE);
tv1.setVisiblity(VISIBLE);
//if the textView is shown, the btn click will hide it and show editText
//instead, and same happens for editText
btn1.setOnClickListener(new View.OnClickListener(){
public void onClick(){
if(et1.getVisiblity() != VISIBLE) {
et1.setVisbility(VISIBLE);
tv1.setVisibility(GONE);
} else {
et1.setVisbility(GONE);
tv1.setVisibility(VISIBLE);
}
} });
P.S: This isn't executable code, although, hopefully it will get you the idea.

Pass data from dialog to activity Android

I have problem.
I made method which creates Dialog with my own layout. And I have no idea how to pass values (Strings) from my EdiText and asing to any variable in my Activity.
In comments you can see how I was trying to solve this.
Java method
public void makeDialog(){
// custom dialog
final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.dialog_ip);
dialog.setTitle("IP connection");
// Todo passing value from dialog to activity
// final EditText ipValueConnection = (EditText)findViewById(R.id.ipValueConnection);
// ipValueConnection.setOnClickListener(this);
// EditText portValueConnection = (EditText)findViewById(R.id.portValueConnection);
// Toast.makeText(context, ipValueConnection.getText().toString(), Toast.LENGTH_LONG).show();
Button dialogButtonLogin = (Button) dialog.findViewById(R.id.dialogButtonLogin);
// if button is clicked, close the custom dialog
dialogButtonLogin.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
tryToConnect();
dialog.dismiss();
}
});
// set the custom dialog components - text, image and button
// TextView text = (TextView) dialog.findViewById(R.id.IP);
dialog.show();
}
XML layout
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:src="#drawable/antena"
android:layout_width="220dp"
android:layout_height="120dp"
android:scaleType="centerInside"
android:background="#FFFFBB33"
android:contentDescription="#string/app_name"
android:adjustViewBounds="true"
/>
<EditText
android:id="#+id/ipValueConnection"
android:inputType="textEmailAddress"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="16dp"
android:layout_marginLeft="4dp"
android:layout_marginRight="4dp"
android:layout_marginBottom="4dp"
android:hint="IP" />
<EditText
android:id="#+id/portValueConnection"
android:inputType="textPassword"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="4dp"
android:layout_marginLeft="4dp"
android:layout_marginRight="4dp"
android:layout_marginBottom="16dp"
android:fontFamily="sans-serif"
android:hint="PORT"/>
<Button
android:id="#+id/dialogButtonLogin"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Login"
android:layout_marginTop="5dp"
/>
</LinearLayout>

Create a interface
public interface OnClickInterface {
public void onClick();
}
call it instantiate it in your activity onCreate()
OnClickInterface onClickInterface = new OnClickInterface() {
#Override
public void onClick() {
//Call Method from here
requiredMethod();
}
};
//And in your dialog classs or method
public void makeDialog(OnClickInterface onClickInterface){
//Your code
dialogButtonLogin.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
onClickInterface.onClick();
dialog.dismiss();
}
});
}

The error you are getting means that a reference to the editText cannot be found in the current layout file. You have find the EditText in the custom dialog view instead of the activity view.
So instead of:
final EditText ipValueConnection =(EditText)findViewById(R.id.ipValueConnection);
use:
final EditText ipValueConnection =(EditText)dialog.findViewById(R.id.ipValueConnection);

If i have understood your question correctly,
your edit text is in dialog_ip so you need to use
final EditText ipValueConnection = (EditText) dialog.findViewById(R.id.ipValueConnection);
Then you can get text from edit text as
String text= ipValueConnection.getText().toString;
And use that variable in your activity.

Buttons of alert dialog are cut off

I have an alert dialog which is started when someone touches a specific button. The alert dialog contains a view that is defined by a layout xml file. This layout contains several controls like check boxes, edit text fields, ... These controls are all inside a scrool view so that you can scroll through the content, if the whole content doesn't fit on the screen.
The problem is now that when I start this alert dialog, the buttons at the bottom are cut off screen. Altough the scrool bar is working and I can scroll through the content of the alert dialog, the buttons of the alert dialog are sometimes not totally visible.
This means:
Sometimes, all is fine and I can see the buttons of the alert dialog, an sometimes for strange reason, the buttons are cut off. I think it's an issue of the view being to big for the alert dialog and pushing the buttons more down.
For example, the view contains an edit text control. If I enter my name ther, everything is fine. But if I add a new line to this edit text, the buttons start to be cut off a little bit.
What did I wrong? I thought the scroll view would handle the oversize of my view so that the alert dialog fits to the screen.
My app is in portrait mode always.
The code of the view:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scrollView2"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="5dp" >
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/bitteeinstellungenwaehlen" />
<EditText
android:id="#+id/edtTeam1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10"
android:hint="#string/hteam1"
android:text="Christoph" >
<requestFocus />
</EditText>
<EditText
android:id="#+id/edtTeam2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10"
android:hint="#string/hteam2"
android:text="Lea" />
<EditText
android:id="#+id/edtTeam3"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10"
android:hint="#string/hteam3"
android:text="Ludwig" />
<EditText
android:id="#+id/edtTeam4"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10"
android:hint="#string/hteam4"
android:text="Anja" />
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/weitereeinstellungen" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<CheckBox
android:id="#+id/chkModerationMode"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/moderationsmodus" />
<TextView
android:id="#+id/textView3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:text="#string/info" />
</LinearLayout>
<CheckBox
android:id="#+id/chkPassOver"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:checked="true"
android:text="#string/weitergeben" />
<CheckBox
android:id="#+id/chkBlackScreen"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/blankscreen" />
</LinearLayout>
</ScrollView>
And that's how I start the alert dialog:
final AlertDialog.Builder alert = new AlertDialog.Builder(QuizEditor.this);
alert.setTitle(getString(R.string.speichernUndVorschau) + "...");
alert.setMessage("");
LayoutInflater inflater = LayoutInflater.from(QuizEditor.this);
final View layFrage = inflater.inflate(R.layout.layoutquizsettings,null);
alert.setView(layFrage);
final CheckBox chkModeration = (CheckBox) layFrage.findViewById(R.id.chkModerationMode);
final CheckBox chkPassOver = (CheckBox) layFrage.findViewById(R.id.chkPassOver);
final CheckBox chkBlackScreen = (CheckBox) layFrage.findViewById(R.id.chkBlackScreen);
final EditText edtTeam1 = (EditText) layFrage.findViewById(R.id.edtTeam1);
final EditText edtTeam2 = (EditText) layFrage.findViewById(R.id.edtTeam2);
final EditText edtTeam3 = (EditText) layFrage.findViewById(R.id.edtTeam3);
final EditText edtTeam4 = (EditText) layFrage.findViewById(R.id.edtTeam4);
alert.setNeutralButton(getString(R.string.speichernUndVorschau), new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
}
});
alert.setNegativeButton(getString(R.string.abbrechen), new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
// Canceled.
}
});
final AlertDialog dialog2 = alert.create();
dialog2.setOnShowListener(new OnShowListener() {
#Override
public void onShow(DialogInterface dialog) {
// TODO Auto-generated method stub
Button btnStarten = (Button) dialog2.getButton(AlertDialog.BUTTON_NEUTRAL);
btnStarten.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
ArrayList<String> teams = new ArrayList<String>();
String team1 = edtTeam1.getText().toString().trim();
String team2 = edtTeam2.getText().toString().trim();
String team3 = edtTeam3.getText().toString().trim();
String team4 = edtTeam4.getText().toString().trim();
if(team1.length() > 0) teams.add(team1);
if(team2.length() > 0) teams.add(team2);
if(team3.length() > 0) teams.add(team3);
if(team4.length() > 0) teams.add(team4);
if(teams.size() == 0) {
Toast.makeText(QuizEditor.this, getString(R.string.keinteameingegeben), Toast.LENGTH_SHORT).show();
}
else
{
// Quiz starten
dialog2.dismiss();
Intent myIntent;
if(chkBlackScreen.isChecked()) {
myIntent = new Intent(QuizEditor.this, BlackScreen.class);
}
else // Direkt das Quiz starten
{
myIntent = new Intent(QuizEditor.this, Quiz.class);
}
myIntent.putStringArrayListExtra("teams", teams);
myIntent.putExtra("moderation", chkModeration.isChecked());
myIntent.putExtra("passover", chkPassOver.isChecked());
myIntent.putExtra("filename", filename);
QuizEditor.this.startActivity(myIntent);
}
}
});
}
});
dialog2.show();
// dialog2.getWindow().setLayout(LayoutParams.WRAP_CONTENT, 300);
I am sorry for the German words. In the image you can see the problem.
Unfortunately I was not allowed to upload the screenshots I made...

The question was already solved in the comments, but I will add an answer for completeness and to show that it worked for me, too.
For an AlertDialog with a custom view, don't use the .setMessage line. Removing the following line in my project caused the buttons to stop getting clipped.
.setMessage("This is my message")

Set EditText lines to 1. Also set outer LinearLayout's to fill_parent.

Just make all the EditText property android:singleLine="true" and then try to test.

Get values from Dynamic list

Good day everyone,
I'm learning Android development and I try to build some dynamic lists for my application. And I'm stuck... like for 4 hours already.
I have two layouts:
1. main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/action_buttons"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:gravity="center"
>
<Button
android:id="#+id/button_count"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/button_calculate" />
<Button
android:id="#+id/button_add"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/button_count"
android:text="#string/button_add" />
</LinearLayout>
<ScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/action_buttons"
>
<LinearLayout
android:id="#+id/action_list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
</LinearLayout>
</ScrollView>
</RelativeLayout>
action_list_item.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/action_list_item_root"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<EditText
android:id="#+id/action_list_item_edittext_drinkName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/action_list_item_button_remove"
android:layout_alignParentTop="true"
android:layout_toRightOf="#+id/action_list_item_title"
android:padding="10dp" />
<EditText
android:id="#+id/action_list_item_edittext_drinkPercent"
android:text="40"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_toLeftOf="#+id/action_list_item_edittext_drinkAmount"
android:inputType="number"
android:padding="10dp"/>
<EditText
android:id="#+id/action_list_item_edittext_drinkAmount"
android:text="0.0"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_toLeftOf="#+id/action_list_item_button_remove"
android:layout_alignBottom="#+id/action_list_item_button_remove"
android:inputType="numberDecimal"
android:width="50dp"
android:padding="10dp" />
<Button
android:id="#+id/action_list_item_button_remove"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="#string/action_list_item_button_remove" />
And code that creates dynamic list:
public class MainActivity extends Activity {
LinearLayout actionList = null;
private Button btnAdd;
private Button btnCalculate;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
initActivityElements();
}
private void initActivityElements() {
initAddButton();
initCalculateButton();
}
private void initCalculateButton() {
btnCalculate = (Button) findViewById(R.id.button_count);
btnCalculate.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
TextView amount = (TextView) findViewById(R.id.action_list_item_edittext_drinkAmount);
//this retrives TextView value from first list
Toast.makeText(getApplicationContext(), amount.getText().toString(),
Toast.LENGTH_SHORT)
.show();
}
});
}
private void initAddButton() {
actionList = (LinearLayout) findViewById(R.id.action_list);
btnAdd = (Button) findViewById(R.id.button_add);
btnAdd.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
RelativeLayout listItem = (RelativeLayout) View.inflate(
MainActivity.this, R.layout.action_list_item, null);
TextView name = (TextView) listItem
.findViewById(R.id.action_list_item_edittext_drinkName);
name.setText("Here is the Title " + actionList.getChildCount());
listItem.findViewById(R.id.action_list_item_button_remove)
.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
actionList.removeView((View) v.getParent());
}
});
actionList.addView(listItem);
}
});
}
My problem is that I need to get all data from TextView boxes (Amount, Percent), but I can retrive that data only from first item of a list (look at onClickListener for btnCalculate) and can't figure out how to do it, but tried to add 'unique ids' for view (but that brakes layout, badly), tried setting Tags but again with no luck.
Maybe anyone can give a tip? I bet there is some easy way to do it, but I'm failing to find it and google is no help here.
Thanks

I'm not really sure what exactly you are trying to do but it sounds like you are trying to take in information and populate it into a view. I would recommend having a static text box that takes in your information and builds that into a listview. A good example of how to do that is located here http://developer.android.com/resources/tutorials/notepad/notepad-ex1.html.
