Question

I have the following issue.

In an activity which is set up in LANDSCAPE mode I have a button.This magical button is set on the right side of the activity and at the bottom of the screen from my point of view.

This is how it looks like: http://i52.tinypic.com/n63rmb.png .

This is the xml file of my activity :

<?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="horizontal">
    <LinearLayout android:layout_width="fill_parent"
    android:layout_height="fill_parent" android:orientation="vertical"
    android:layout_weight="1.0">
      <SurfaceView  
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
   android:id="@+id/surface_camera"
    />

    </LinearLayout>
    <LinearLayout android:layout_width="wrap_content"
    android:layout_height="500px">
        <Button 
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" 
    android:id="@+id/btnPhoto"
    android:text="Take Photo"
    android:layout_gravity="bottom|left" 
/>
    </LinearLayout>
</LinearLayout>

And this is the animation I do with the button:

takePhoto = (Button) findViewById(R.id.btnPhoto);
        takePhoto.setText(t);
        RotateAnimation ranim = (RotateAnimation)AnimationUtils.loadAnimation(this, R.anim.myanim);
          ranim.setFillAfter(true);
        takePhoto.setAnimation(ranim);

And finally this is res/anim/myanim xml file:

<?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" />

Now please tell me how to increase the width of that button, please.Thank you

BTW: I tried this:

        Display display=getWindowManager().getDefaultDisplay();
        width=display.getWidth();
        height=display.getHeight();
        takePhoto.setWidth(width);

But there is no change at all!

Answer 1

There is two problem in your code…first one is due to animation…comment your animation code…or change it…I run your code after commenting it out…

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

And second problem is layout, try this layout for your R.layout.takephoto

<?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"
android:orientation="horizontal">
<Button android:layout_width="fill_parent"
    android:layout_height="45dp" android:id="@+id/btnPhoto" android:text="Take Photo"
    android:layout_alignParentBottom="true" />
<SurfaceView android:layout_width="fill_parent"
    android:layout_height="fill_parent" android:id="@+id/surface_camera"
    android:layout_above="@id/btnPhoto" />
 </RelativeLayout>

One suggestion: Try to use RelativeLayout….it will simplify your layout.
