问题
In my application I need to record by camera. During recording I show some items as menu on screen. I need to slide out menu from screen when user clicks an arrow and slide it in when user touched the screen.
I have two problem. 1) It seems my animation doesn't work. 2) when i set RelativeLayout to visible/invisible just the view take effect, camera view doesn't get the whole of screen as you see in images (I don't want see black background).
R.anim.slide_in_up:
<?xml version="1.0" encoding="utf-8"?>
<translate
xmlns:android = "http://schemas.android.com/apk/res/android"
android:fromYDelta = "100%p"
android:toYDelta = "0%p"
android:duration = "3000" />
R.anim.slide_out_up:
<?xml version="1.0" encoding="utf-8"?>
<translate
xmlns:android = "http://schemas.android.com/apk/res/android"
android:fromYDelta = "0%p"
android:toYDelta = "100%p"
android:duration = "3000" />
Code, for showing slide_in_up:
rlMenu = (RelativeLayout) findViewById(R.id.rlMenu);
imHide = (ImageView) findViewById(R.id.btn_hide);
imHide.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
rlMenu.setVisibility(View.INVISIBLE);
overridePendingTransition(R.anim.slide_in_up, R.anim.slide_out_up);
}
});
Code, for showing slide_out_up:
@Override
public boolean onTouchEvent(MotionEvent event) {
rlMenu.setVisibility(View.VISIBLE);
overridePendingTransition(R.anim.slide_out_up, R.anim.slide_in_up);
return super.onTouchEvent(event);
}
Screen layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android = "http://schemas.android.com/apk/res/android"
android:layout_width = "fill_parent"
android:layout_height = "fill_parent"
android:orientation = "vertical" >
<FrameLayout
android:id = "@+id/camera_preview"
android:layout_width = "fill_parent"
android:layout_height = "0dip"
android:layout_weight = "1" />
<RelativeLayout
android:id = "@+id/rlMenu"
android:layout_width = "fill_parent"
android:layout_height = "wrap_content"
android:orientation = "horizontal" >
<RelativeLayout
android:layout_width = "240dip"
android:layout_height = "50dip"
android:background = "@drawable/btn_top_edge_right"
android:layout_alignParentLeft = "true" >
<ImageView
android:id = "@+id/btn_hide"
android:layout_width = "40dip"
android:layout_height = "wrap_content"
android:src = "@drawable/btn_record_hide"
android:layout_marginTop = "10dip"
android:layout_marginBottom = "10dip"
android:contentDescription = "@string/menu_contentdescription"
android:scaleType = "fitXY" />
<ImageView
android:id = "@+id/btn_record"
android:layout_width = "wrap_content"
android:layout_height = "wrap_content"
android:src = "@drawable/btn_record_start"
android:layout_toRightOf = "@id/btn_hide"
android:layout_margin = "10dip"
android:contentDescription = "@string/menu_contentdescription" />
<ImageView
android:id = "@+id/btn_stop"
android:layout_width = "wrap_content"
android:layout_height = "wrap_content"
android:src = "@drawable/btn_record_stop"
android:layout_toRightOf = "@id/btn_record"
android:layout_marginTop = "10dip"
android:layout_marginBottom = "10dip"
android:contentDescription = "@string/menu_contentdescription"
android:clickable = "false" />
</RelativeLayout>
<Button
android:id = "@+id/btn_done"
android:layout_width = "wrap_content"
android:layout_height = "50dip"
android:background = "@drawable/btn_record_done"
android:layout_alignParentRight = "true"
android:text = "@string/Record_btn"
android:paddingLeft = "15dip"
style = "@style/simpletopic.bold" />
</RelativeLayout>
</LinearLayout>
How can I remove the whole of RelativeLayout and enlarge camera view with my animation? Thanks

Answer to second question. Try changing your layout as below:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<FrameLayout
android:id="@+id/camera_preview"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
<RelativeLayout
android:id="@+id/rlMenu"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:orientation="horizontal" >
<ImageView
android:id="@+id/btn_hide"
android:layout_width="40dip"
android:layout_height="wrap_content"
android:layout_marginBottom="10dip"
android:layout_marginTop="10dip"
android:contentDescription="@string/menu_contentdescription"
android:scaleType="fitXY"
android:src="@drawable/btn_record_hide" />
<ImageView
android:id="@+id/btn_record"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="10dip"
android:layout_toRightOf="@id/btn_hide"
android:contentDescription="@string/menu_contentdescription"
android:src="@drawable/btn_record_start" />
<ImageView
android:id="@+id/btn_stop"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="10dip"
android:layout_marginTop="10dip"
android:layout_toRightOf="@id/btn_record"
android:clickable="false"
android:contentDescription="@string/menu_contentdescription"
android:src="@drawable/btn_record_stop" />
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:orientation="horizontal" >
<Button
android:id="@+id/btn_done"
style="@style/simpletopic.bold"
android:layout_width="wrap_content"
android:layout_height="50dip"
android:layout_alignParentRight="true"
android:background="@drawable/btn_record_done"
android:paddingLeft="15dip"
android:text="@string/Record_btn" />
</LinearLayout>
</RelativeLayout>
</RelativeLayout>
I had a similar situations with a custum MapView.

I think this will work out if you use frame layout.Add two frames and add the pictures to the frame.Alternatively adding the animation to the two frames and making it play will make this work out.I think this will work and give you what you wanted.A small piece of code is shown below hope this will help you a lil bit.
if (imagesetflag == true) {
Right_to_left_in = AnimationUtils.loadAnimation(this,
R.anim.right_to_left_in);
Right_to_left_out = AnimationUtils.loadAnimation(this,
R.anim.right_to_left_out);
left_to_Right_in = AnimationUtils.loadAnimation(this,
R.anim.left_to_right_in);
Left_to_Right_out = AnimationUtils.loadAnimation(this,
R.anim.left_to_right_out);
frame1.setImageBitmapReset(decryptedimage, 0, true);
frame1.bringToFront();
frame1.setVisibility(View.VISIBLE);
frame2.setVisibility(View.INVISIBLE);
frame1.setAnimation(Right_to_left_in);
frame2.setAnimation(Right_to_left_out);
} else {
Right_to_left_in = AnimationUtils.loadAnimation(this,
R.anim.right_to_left_in);
Right_to_left_out = AnimationUtils.loadAnimation(this,
R.anim.right_to_left_out);
left_to_Right_in = AnimationUtils.loadAnimation(this,
R.anim.left_to_right_in);
Left_to_Right_out = AnimationUtils.loadAnimation(this,
R.anim.left_to_right_out);
frame2.setImageBitmapReset(decryptedimage, 0, true);
frame2.bringToFront();
frame2.setVisibility(View.VISIBLE);
frame1.setVisibility(View.INVISIBLE);
frame2.setAnimation(Right_to_left_in);
frame1.setAnimation(Right_to_left_out);
}

Just try to set visibility GONE to other layout elements, so main view will get stretched.
