Если кто-то может сказать мне, где я здесь не так, это было бы здорово, если бы я потратил около 2 дней, чтобы попытаться выяснить (Google) это.По сути, я просто хочу изменить layout_height корневого linearlayout с wrap_content на fill_parent, когда пользователь нажимает кнопку.
вот мой корень main.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/mycontainer"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="#ffff00ff">
<Button android:id="@+id/listBtn"
android:layout_height="38dp"
android:layout_width="wrap_content"
android:text="List"
android:onClick="listBtnHandler"
android:paddingLeft="17dp"
android:paddingRight="17dp"
android:layout_gravity="center"
android:layout_marginRight="10dip"/>
</LinearLayout>
А вот мой кодэто вызывает ошибку.
public class MainActivity extends Activity {
/** Called when the activity is first created. */
private Button listBtn;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
listBtn = (Button) findViewById(R.id.listBtn);
}
public void listBtnHandler(View v) {
Log.i("eb", "my button worked");
LinearLayout ll = (LinearLayout) findViewById(R.id.mycontainer);
ll.setLayoutParams(new LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT));
//ViewGroup.LayoutParams params = ll.getLayoutParams();
//params.height=300;
//ll.setLayoutParams(new LinearLayout.LayoutParams(params));
//ll.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.FILL_PARENT));
}
}
Само собой разумеется, я не могу заставить что-либо работать здесь.
Вот вывод консоли, и он не 'не могу показать что-либо релевантное, так как я получаю источник не найден.
Application already deployed. No need to reinstall.
