Hi:
I created a view whose layout like:
TextView Button Button
ListView
Everything works fine at touch mode. But weird thing happens when
I try to focus the listview item using trackball. The items in
listView can not be focused. I post my layout file and code, you can
try it on device or emulator. Is there anyone can help me to figure
out where I am doing wrong? thanks a lot in advance.
Here is my xml file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/
android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<LinearLayout android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="left"
android:text="@string/hello"
/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:text="@string/hello"
android:id="@+id/button1"
/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:text="@string/hello"
android:id="@+id/button2"
/>
</LinearLayout>
<ListView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="@+id/listviewId"/>
</LinearLayout>
And my code is below:
public class MainActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ListView listView = (ListView) findViewById(R.id.listviewId);
Button headerBtn = new Button(this);
headerBtn.setWidth(LayoutParams.FILL_PARENT);
headerBtn.setHeight(LayoutParams.WRAP_CONTENT);
headerBtn.setText("ListView Header");
listView.addHeaderView(headerBtn);
Button button1 = (Button)findViewById(R.id.button1);
button1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(MainActivity.this, "Button1",
2000).show();
}
});
Button button2 = (Button)findViewById(R.id.button2);
button2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(MainActivity.this, "Button2",
2000).show();
}
});
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1);
for (int i = 0; i < 20; ++i) {
adapter.add("value" + i);
}
listView.setAdapter(adapter);
listView.setItemsCanFocus(true);
listView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1,
int arg2,
long arg3) {
Toast.makeText(MainActivity.this, "Value" +
arg2, 2000).show();
}
});
}
}
