Question

I have an activity in android which I set up a button under a SurfaceView. And the result looks like this:

And I’m satisfied with it except one thing, the writing on the button is astray and must be setup correctly.
For this I used animations like this:

takePhoto = (Button) findViewById(R.id.btnPhoto);
takePhoto.setText(t);

RotateAnimation ranim = (RotateAnimation)AnimationUtils.loadAnimation(this, R.anim.myanim);
ranim.setFillAfter(true);
takePhoto.setAnimation(ranim);

WHERE the res/anim/myanim looks like:

<?xml version="1.0" encoding="utf-8"?>
<rotate  xmlns:android="http://schemas.android.com/apk/res/android"
       android:fromDegrees="0" 
       android:toDegrees="-90"
       android:pivotX="50%"
       android:pivotY="50%"
       android:duration="0" />

But the result is a little bit disappointing cause the whole looks like:

The text is ok, but the dimensions are reduced.

What I want is to keep the text correctly and the initial size.How could I do that???
It has nothing to do with the button’s properties in the xml file cause I haven’t changed them when loading the animation….Ideas?Thanks…

EDIT: xml file

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout android:layout_width="fill_parent"
android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"
>

<SurfaceView android:layout_width="450dip"
android:layout_height="fill_parent" android:id="@+id/surface_camera" />

<RelativeLayout android:layout_width="fill_parent"
android:layout_toRightOf="@id/surface_camera"
android:layout_height="fill_parent"
 >

<Button android:layout_width="680dip"
android:layout_height="680dip" 
android:id="@+id/btnPhoto"
android:layout_alignParentBottom="true"
android:text="Take Photo" 
android:layout_gravity="bottom|right" />

</RelativeLayout>

</RelativeLayout>





IMPORTANT:

In the cases described below...my activity is in `LANDSCAPE` mode and the position of the phone is portrait.Another issue is that when I turn my phone in landscape mode(and here I mean the position of the phone, cause the activity is still landscape) the button doesn't go at the bottom of the phone is stays there.No matter how I turn the phone the button is in the same position!!!!

Answer 1

You should read this

Make two layout folders like follows …

In both of folders your layout file name should be same.

In layout-port folder your layout file should look like this …

android:layout_toRightOf="@id/surface_camera"

replaced by …

android:layout_Below="@id/surface_camera"

as follows …

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout android:layout_width="fill_parent"
android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"
>

<SurfaceView android:layout_width="450dip"
android:layout_height="fill_parent" android:id="@+id/surface_camera" />

<RelativeLayout android:layout_width="fill_parent"
android:layout_toBelow="@id/surface_camera" 
android:layout_height="fill_parent"
 >

<Button android:layout_width="680dip"
android:layout_height="680dip" 
android:id="@+id/btnPhoto"
android:layout_alignParentBottom="true"
android:text="Take Photo" 
android:layout_gravity="bottom|right" />

</RelativeLayout>

</RelativeLayout>

Even this will considered as bad practice but you can also handle this manually, try this ..

    @Override
    public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       //setContentView(R.layout.main);

      int orientation = getResources().getConfiguration().orientation;

      if(orientation == Configuration.ORIENTATION_PORTRAIT) {
         setContentView(R.layout.main1);

      }
      else {

         setContentView(R.layout.main2);
      }
   }

Also If you are doing this way No need to make two layout folders, but needs two layout files main1 and main2 in same folder

Yet another option …

In manifest …

<activity android:name=".ActivityName" android:configChanges="keyboardHidden|orientation">

+

In your Activity …

 @Override
    public void onConfigurationChanged(Configuration newConfig) {
      super.onConfigurationChanged(newConfig);

      int orientation = newConfig.orientation;
      if(orientation == Configuration.ORIENTATION_PORTRAIT) {

        setContentView(R.layout.main2);
      }
      else {

        setContentView(R.layout.main);
      }
    }
