After that also when I clicked the button image will rotate. but positions is changed and not shown in full screen.
My requrement is, when I click the button image will be roatate clockwise and will show in full screen. Again I click the button image must be rotate clock wise and show in full screen. Likewise when I click the button image must be rotate.
Therefore can someone help me? If you can give me a sample code or a link that will be very much appriciated.
Here is the code which I'm trying,
main.xml
<merge xmlns:android="http://schemas.android.com/apk/res/android" >
<ImageView
android:id="@+id/imgView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:scaleType="fitXY"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:adjustViewBounds="true"
android:src="@drawable/matterhorn"
/>
<Button
android:id="@+id/btnRotate"
android:layout_width="65dp"
android:layout_height="35dp"
android:layout_gravity="bottom|left"
android:layout_marginLeft="190dp"
android:layout_marginBottom="15dp"
android:layout_weight="1"
android:background="@android:color/transparent"
android:drawableLeft="@drawable/btn_icon_rotate"
>
</Button>
</merge>
This is my main activity "MainActivity.java"
package com.imageview.rotate;
import android.os.Bundle;
import android.app.Activity;
import android.graphics.Matrix;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.ImageView.ScaleType;
public class MainActivity extends Activity implements OnClickListener{
private Button btnRotate;
private ImageView imgview;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
imgview = (ImageView) findViewById(R.id.imgView);
btnRotate = (Button) findViewById(R.id.btnRotate);
btnRotate.setOnClickListener(this);
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btnRotate:
Matrix matrix=new Matrix();
imgview.setScaleType(ScaleType.MATRIX); //required
matrix.postRotate((float) 180f, imgview.getDrawable().getBounds().width()/2, imgview.getDrawable().getBounds().height()/2);
imgview.setImageMatrix(matrix);
break;
}
}
}
Thanks in advance.
Create button_rotate.xml
in anim
folder:
<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="1000"
android:fromDegrees="0"
android:interpolator="@android:anim/linear_interpolator"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="360" />
Now create animation in Java file:
/* Get ImageView Object */
ImageView iv = (ImageView) view.findViewById(R.id.refresh_action_view);
/* Create Animation */
Animation rotation = AnimationUtils.loadAnimation(context, R.anim.refresh_button_anim);
rotation.setRepeatCount(Animation.INFINITE);
/* start Animation */
iv.startAnimation(rotation);
For stop animation:
iv.clearAnimation();
