I am creating an project of android application by linking MySQL database using PHP. I am facing a problem that the click event on a button in sliding drawer is not working.
layout of sliding drawer
<SlidingDrawer
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/sliding"
android:handle="#+id/handle"
android:content="#+id/content"
android:clickable="true"
>
<Button
android:layout_width="60dp"
android:layout_height="60dp"
android:id="#+id/handle"
android:background="#drawable/up"
/>
<ScrollView
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:id="#+id/content"
android:clickable="true"

</LinearLayout>
</ScrollView>
</SlidingDrawer>
Java code:
fmenu=(Button) findViewById(R.id.foodmenutv);
handle=(Button) findViewById(R.id.handle);
sliding=(SlidingDrawer) findViewById(R.id.sliding);
sliding.setOnDrawerOpenListener(new SlidingDrawer.OnDrawerOpenListener() {
#Override
public void onDrawerOpened() {
handle.setBackgroundResource(R.drawable.down);
//sliding.unlock();
}
});
sliding.setOnDrawerCloseListener(new SlidingDrawer.OnDrawerCloseListener() {
#Override
public void onDrawerClosed() {
handle.setBackgroundResource(R.drawable.up);
}
});
fmenu.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(context,"hell",Toast.LENGTH_LONG).show();
// setContentView(R.layout.activity_foodmenu);
}
});
Please try after removing the clickable="true" property in your Layout.May be that causes the problem

Closed 4 years ago.
This is the code MainActivity.java file. I think there should be no mistake in this code. But it shows the message
Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'android.view.Window$Callback android.view.Window.getCallback()' on a null object reference.
I don't know why it is showing up there? Please help me to figure out.

Here is the image of it should look like it is the screenshot the preview
All these findViewById must be included in your onCreate() method. You can keep the declarations out of onCreate(). Your views do not exist before setContentView(R.layout.activity_main);
I mean before onCreate() you can have Button b1;
and after setContentView(R.layout.activity_main); in onCreate() you must have b1=(Button)findViewById(R.id.b_i1);
for every view.
I have made the corrections in your and now the app is not crashing. Try using the below code snippet
MainActivity
public class MainActivity extends AppCompatActivity {
int score = 0, wickets = 0;

Hope this helps.
On my android app I have two horizontal scroll views that act as docks. How can I make it so that if button 1 is clicked dock 1 displays and if button 2 is clicked dock 2 displays? Since they're docks I want them to both display in the same position.
here is my code:
<HorizontalScrollView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="50dp">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button1" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button2" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button3" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button4" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button5" />
</LinearLayout>
</HorizontalScrollView>
<HorizontalScrollView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="50dp">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button1" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button2" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button3" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button4" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button5" />
</LinearLayout>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="dockButton1" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="dockButton2" />
Button code:
dock1button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
}
});
dock2button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
}
});
Step 1:
add id in both of the HorizontalScrollView
for example: android:id="#+id/hScrollView1" and android:id="#+id/hScrollView2"
Step 2:
Put both HorizontalScrollView in a parent LinearLayout like below:
<LinearLayout>
<HorizontalScrollView
android:id="#+id/hScrollView1">
.
.
</HorizontalScrollView>
<HorizontalScrollView
android:id="#+id/hScrollView2">
.
.
</HorizontalScrollView>
</LinearLayout>
Step 3:
In your button click just toggle the visibility:
in onClick just use..
hScrlView1.setVisibility(View.GONE);
hScrlView2.setVisibility(View.VISIBLE);
and
hScrlView1.setVisibility(View.VISIBLE);
hScrlView2.setVisibility(View.GONE);
where hScrlView1 and hScrlView2 are the ScrollView you want to show.
put the two horizontal listviews in a relative layout and set the visibility of one of them to invisible.
<?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:text="Button5" />
</LinearLayout>
</HorizontalScrollView>
<HorizontalScrollView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="50dp"
android:visibility="invisible" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button1" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button2" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button3" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button4" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button5" />
</LinearLayout>
</HorizontalScrollView>
</RelativeLayout>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="dockButton1" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="dockButton2" />
then change the visibility in buttons' codes:
Button code:
dock1button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
horizontalList2.setVisibilty(View.INVISIBLE);
horizontalList1.setVisibilty(View.VISIBLE);
}
});
dock2button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
horizontalList1.setVisibilty(View.INVISIBLE);
horizontalList2.setVisibilty(View.VISIBLE);
}
});
You'd be better off by just using FrameLayout containing both scrollviews. It would be more performant than using LinearLayout or even worse RelativeLayout.
Just do something like this (schematic code, some xml attrs omitted)
<FrameLayout>
<HorizontalScrollView
android:id="#+id/view1"/>
<HorizontalScrollView
android:id="#+id/view2"
android:visibility="gone"
/>
</FrameLayout>
And then in your onClick handler(s) do something like
view1.setVisibility(View.VISIBLE)
view2.setVisibility(View.GONE)
or vice versa (depending on button pressed)
Strangely, my listView's onClick no longer works after I added two Buttons: Submit and Show Result.
Here is the list view xml.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

Here is the click snippet of the list view:
listview.setOnItemClickListener( new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View view,
int position, long id) {
long audit_id;
try{
audit_id = (new CustomListAdapter(HomeList.this, c).getAuditID(position));
changeTileStatus(audit_id,"opened");
System.out.println("listClicked");
sendAuditAndIntent(audit_id);
}catch(Exception e)
{
System.out.println("ERROR # HOMELIST list onClick: "+e);
}
}
private void sendAuditAndIntent(long audit_id) { //sends audit id and api key
Intent intent = new Intent(HomeList.this,ChapterActivity.class );
Bundle extras= new Bundle();
extras.putString("audit_id",String.valueOf(audit_id));
extras.putString("api_key", api_key);
intent.putExtras(extras);
startActivity(intent);
}
private void changeTileStatus(long audit_id, String value) {
AuditTableManager tile= new AuditTableManager(HomeList.this);
tile.open();
tile.updateEntry(audit_id, value);
tile.close();
}
});
OnItemClickListener is not called if cells contain clickable Views. It is an Android feature. You can handle clicks by OnClickListener then - set it to your two buttons (not the listView itself).
In your adapter:
public View onCreateView(..., final int position){
...
convertView.findViewById(R.id.button1).setOnClickListener(new OnClickListener(){
public void onClick(View view){
itemClickedAction1(position);
}
});
convertView.findViewById(R.id.button2).setOnClickListener(new OnClickListener(){
public void onClick(View view){
itemClickedAction2(position);
}
});
...
}
Try android:Focusable="false" and also android:clickable="false" in the custom row TextView
I am trtying to create this layout below, but I can seem to get the right
layout that I need. What I'm trying to accomplish is have a customize dailog box,
using a layout. I tried edit the xml below but if this is shown as a dialog the
defined layout is a mess. Please help me understand what I need to do for
this. THanks and looking forward. They dialog is SHOWING but the layout is not met.
This layout is what I am trying to accomplish:
Dialog:
View checkBoxView = View.inflate(this, R.layout.display_item_dialog, null);
CheckBox checkBox = (CheckBox)checkBoxView.findViewById(R.id.checkBox1);
checkBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
// Save to shared preferences
}
});
checkBox.setText("Search All Images");
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Image Preferences");
builder.setMessage(" Select from below ")
.setView(checkBoxView)
.setCancelable(false)
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
}
})
.setNegativeButton("No", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
}).show();
