Thanks for the answer, I solved the problem with remove the view from the linearlayout like this:
public void onAnimationEnd(Animator animation) {
parent.removeView(this.v);
lv.setTranslationY(0);
}
Question
I have a Button, a View and a ListView in my LinearLayout. On button click event I want view to disappear and the listview is take its place. I tried to set LayoutParams to match_parent dinamically after the animation but it doesn't work. Any ideas?
Here is my activity_main.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.example.linearlayouttry.MainActivity" >
<Button android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Start"/>
<View android:id="@+id/view"
android:layout_width="fill_parent"
android:background="@android:color/black"
android:layout_height="300dp"/>
<ListView android:id="@+id/listv"
android:layout_width="match_parent"
android:layout_height="match_parent">
</ListView>
</LinearLayout>
Here is my MainActivity.java:
public class MainActivity extends Activity implements OnClickListener {
protected View v;
protected ListView lv;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ArrayList<String> list = new ArrayList<String>(Arrays.asList("1","2","3","4","5","6","7","8","9","10"));
lv = (ListView) findViewById(R.id.listv);
lv.setAdapter(new ArrayAdapter<>(getApplicationContext(), android.R.layout.simple_list_item_1, list));
Button mButton = (Button) findViewById(R.id.button);
mButton.setOnClickListener(this);
v = findViewById(R.id.view);
}
@Override
public void onClick(View v) {
this.v.setAlpha(0);
int height = this.v.getLayoutParams().height;
lv.animate().translationY(-height).setListener(new AnimatorListener() {
public void onAnimationStart(Animator animation) {}
public void onAnimationRepeat(Animator animation) {}
@Override
public void onAnimationEnd(Animator animation) {
lv.getLayoutParams().height=LayoutParams.MATCH_PARENT;
lv.requestLayout();
}
public void onAnimationCancel(Animator animation) {}
});
}
}
It's working when I set a specific integer to height, but how can I do it with match_parent?
SOLVED:
I only had to remove the view from the linearlayout like this:
public void onAnimationEnd(Animator animation) {
parent.removeView(this.v);
lv.setTranslationY(0);
}

OTHER TIPS
Try
lv.setLayoutParams(new LayoutParams(widthValue, LayoutParams.MATCH_PARENT));
Instead of
lv.getLayoutParams().height=LayoutParams.MATCH_PARENT;
lv.requestLayout();
More info about the LayoutParams class can be found here.
alternatively,
public void onAnimationEnd(Animator animation) {
this.v.setVisibility(View.GONE);
lv.setTranslationY(0);
}
