I have a dialog that I launch with:
// custom dialog
final Dialog dialog = new Dialog(this);
dialog.setContentView(R.layout.add_taste_dialog);
dialog.setTitle("Add Taste");
Spinner spinner = (Spinner) dialog.findViewById(R.id.spinner1);
Spinner spinner2 = (Spinner) dialog.findViewById(R.id.spinner2);
Button dialogButton = (Button) dialog.findViewById(R.id.cancelButton);
// if button is clicked, close the custom dialog
dialogButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
dialog.dismiss();
}
});
dialog.show();
The problem is that when I click the button it does not dismiss the dialog.
My dialog xml is:
<?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"

</LinearLayout>
</LinearLayout>
Here is the full taste tag java code to give the snipet above some more context:
public class TasteTags extends Activity {
BeerData e;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tastetag_page);
//get beer data
Intent intent = getIntent();
Bundle b = intent.getExtras();
e = b.getParcelable("myBeerObject");
TextView beerTitle = (TextView) findViewById(R.id.beerTitleTaste);
beerTitle.setText(e.beerName + " Taste Profile");
String url = "myURL";
url = url + "b=" +e.beerId;
//async task to get beer taste tag percents
new GetTasteJSON(this).execute(url);
}
public void addTaste(View v){
// custom dialog
final Dialog dialog = new Dialog(this);
dialog.setContentView(R.layout.add_taste_dialog);
dialog.setTitle("Add Taste");
Spinner spinner = (Spinner) dialog.findViewById(R.id.spinner1);
Spinner spinner2 = (Spinner) dialog.findViewById(R.id.spinner2);
Button dialogButton = (Button) dialog.findViewById(R.id.cancelButton);
// if button is clicked, close the custom dialog
dialogButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Log.d("dialog", "cancel pressed");
dialog.dismiss();
}
});
dialog.show();
}
}
make final Dialog dialog = null; a global variable (activity level), remove the final and initialize at it where you have it right now, that is fine.
Looking at your code nothing jumps out, if you post your full code or a simple example to replicate i'm sure someone could fully decipher the problem. I have included some sample snippets that show a dialog that work, take a look at those to see if they shed any insight as to why yours does not work.
One thing to check before looking at the working sample, make sure you don't have a button in your dialog view with id 'cancelButton' defined twice(common from copy/paste errors). This will cause the behavior you are seeing. If you take the working example below and use the following view it will reproduce your behavior:
Broken Dialog View

At any devices we have different position of progressBar inside of the progressDialog. So I need to customize it.
When I try like this:
public class CustomProgressDialog extends ProgressDialog {
public CustomProgressDialog(Context context) {
super(context);
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.progress_fragment_dialog);
}
}
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

<ProgressBar
android:layout_width="wrap_content"
android:layout_gravity="center"
android:background="#color/colorPrimary"
android:layout_height="match_parent"
android:id="#+id/progressBar" />
</LinearLayout>
This progress dialog shows only progressBar without dialog. But I need dialog too.
Create custom dialog with progress bar in it for making it consistent for different devices.
final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.custom);
dialog.setTitle("Title...");
// set the custom dialog components - title, ProgressBar and button
TextView text = (TextView) dialog.findViewById(R.id.text);
text.setText("COUSTOM PROGRESS TITLE");
ProgressBar prog = (ProgressBar) dialog.findViewById(R.id.myprogress);
prog.setVisibilty(VISIBLE);
Button dialogButton = (Button) dialog.findViewById(R.id.dialogButtonOK);
// if button is clicked, close the custom dialog
dialogButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
dialog.show();
layout:
<?xml version="1.0" encoding="utf-8"?>

I want to have a spinner which will contain a list of items.
The design I want is as follow:
I tried to put background for the spinner so now it only shows a background. I want white layout inside and with separator.
I tried to create a layout for the item and apply to the spinner but it gives error :
Process: com.kiranaapp, PID: 16697
java.lang.IllegalStateException: ArrayAdapter requires the resource ID to be a TextView
My design now looks like this:
And onclick of spinner I get layout like this:
But I want the list to be shown onClick of TextInputLayout.

How can I achieve this design? Can anyone help with this please? Thank you..
Use ListView or RecyclerView and put a spinner in a layout that will be use in your viewholder.class associated with getView method in adapter class, after-that set your data using ArrayList/Hashmap with the help of constructor of Adapter class.
Follow this
package com.example.spinner;
import java.util.ArrayList;
import java.util.List;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Spinner;
import android.widget.Toast;
import android.widget.AdapterView.OnItemSelectedListener;
class AndroidSpinnerExampleActivity extends Activity implements OnItemSelectedListener{
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// Spinner element
Spinner spinner = (Spinner) findViewById(R.id.spinner);
// Spinner click listener
spinner.setOnItemSelectedListener(this);
// Spinner Drop down elements
List<String> categories = new ArrayList<String>();
categories.add("Automobile");
categories.add("Business Services");
categories.add("Computers");
categories.add("Education");
categories.add("Personal");
categories.add("Travel");
// Creating adapter for spinner
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, categories);
// Drop down layout style - list view with radio button
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
// attaching data adapter to spinner
spinner.setAdapter(dataAdapter);
}
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
// On selecting a spinner item
String item = parent.getItemAtPosition(position).toString();
// Showing selected spinner item
Toast.makeText(parent.getContext(), "Selected: " + item, Toast.LENGTH_LONG).show();
}
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
}
Use this layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:padding="10dip"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dip"
android:text="Category:"
android:layout_marginBottom="5dp"/>
<Spinner
android:id="#+id/spinner"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:prompt="#string/spinner_title"/>
</LinearLayout>
Draw your layout somthing like this:
<RelativeLayout
android:id="#+id/spinner_layout"
android:layout_width="match_parent"
android:layout_height="#dimen/dp_30"
android:layout_margin="#dimen/dp_20"
android:background="#color/fragment_bg"
android:orientation="horizontal">
<TextView
android:id="#+id/txt_city"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginStart="#dimen/dp_20"
android:hint="#string/select_city"
android:singleLine="tru
android:textSize="#dimen/sp_15"/>
<Spinner
android:id="#+id/spinner_city"
android:layout_width="match_parent"
android:layout_height="#dimen/dp_30"
android:layout_centerVertical="true"
android:entries="#array/StateName"
android:gravity="center"
android:padding="#dimen/sp_15"
app:binding="#{location.locations}"/>
</RelativeLayout>
and use your textinput layout instead of textview
Don't use Edittext use Textview to set clicked item text. "if you use edittext, then you have to tap two times to get call in onClickListener method because on first time of click it set to get focus and open soft keyboard"
I'm making an app that needs to be easily read in the dark. By default, the screen is white, and this can be tough on the eyes of the user. The main activity that the user sees to start off with is called Menu, and I would like this to have a black background all over, with white text. I have everything how I want colour-wise, except for my ListView, where it looks black, but I cannot see the text because the background is black as well.

You can add a dark background to the List view. down load a black png image and place in the drawable folders.Example is show
android:background="#drawable/some_black_image"
<ListView
android:id="#android:id/list"
android:layout_width="wrap_content"
android:layout_height="320dp"
android:layout_above="#+id/settings_button"
android:layout_below="#+id/ic_launcher"
android:textColor="#FFFFFF"
android:background="#drawable/some_black_image"
tools:listitem="#android:layout/simple_list_item_1" >
</ListView>
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:

android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_toLeftOf="#+id/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.
I'm a beginner in android and making my first app. Here, I had taken 3 textViews and a button named Add. When I click on this button, I need to show the content of 2 textViews on third textView. I used eventListener and buttonClick event but it doesn't work. Please guide me with the code of Add button.
First create the xml as below:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:layout_gravity="center_horizontal"
android:orientation="horizontal"
android:layout_weight="1"
android:id="#+id/singleEmployee"
android:background="#ffffff">
<TextView
android:text="TextView"
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView
android:text="TextView"
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView
android:text="TextView"
android:id="#+id/textView3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<Button
android:text="Button"
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
And then use this Java code to done your desire action:
public class MainActivity extends Activity {
/** Called when the activity is first created. */
TextView tv1,tv2,tv3;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.testing);
tv1 = findViewById(R.id.textView1);
tv2 = findViewById(R.id.textView2);
tv3 = findViewById(R.id.textView3);
tv1.setText("Hello");
tv2.setText("World");
Button add = findViewById(R.id.button1);
add.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
tv3.setText("");
String tvValue1 = tv1.getText().toString();
String tvValue2 = tv2.getText().toString();
tv3.setText("Value of First Text is: "+tvValue1+".And the value of second TextView is: "+tvValue2);
}
});
}
