I am creating swipe action in my android app. Its working perfectly. Now I want to create set as wallpaper option so that user can set current image as wallpaper. I add some code. But its not working. Please someone help me to make current image as wallpaper.
Code-
public class FullImageActivity extends Activity {
int position;
LinearLayout full;
Button btn;
public Integer[] mThumbId = {
R.drawable.kri1, R.drawable.kri2,
R.drawable.kri3, R.drawable.kri4,
R.drawable.kri5, R.drawable.kri6,
R.drawable.kri7, R.drawable.kri8,
R.drawable.kri9
};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.full_image);
// get intent data
Intent i = getIntent();
// Selected image id
position = i.getExtras().getInt("id");
full = (LinearLayout) findViewById(R.id.full);
btn = (Button)findViewById(R.id.btn);
changeBackground();
btn.setOnClickListener(new Button.OnClickListener(){
@Override
public void onClick(View arg0) {
WallpaperManager myWallpaperManager = WallpaperManager.getInstance(getApplicationContext());
try {
myWallpaperManager.setResource(mThumbId[position]);
} catch (IOException e) {
e.printStackTrace();
}
}});
ActivitySwipeDetector activitySwipeDetector = new ActivitySwipeDetector(this);
full.setOnTouchListener(activitySwipeDetector);
}
private void changeBackground(){
full.setBackgroundResource(mThumbId[position]);
}
public class ActivitySwipeDetector implements View.OnTouchListener {
static final String logTag = "ActivitySwipeDetector";
static final int MIN_DISTANCE = 100;
private float downX, upX;
Activity activity;
public ActivitySwipeDetector(Activity activity){
this.activity = activity;
}
public void onRightToLeftSwipe(){
Log.i(logTag, "RightToLeftSwipe!");
if(position < mThumbId.length - 1){
position++;
changeBackground();
}
}
public void onLeftToRightSwipe(){
Log.i(logTag, "LeftToRightSwipe!");
if(position > 0){
position--;
changeBackground();
}
}
public boolean onTouch(View v, MotionEvent event) {
switch(event.getAction()){
case MotionEvent.ACTION_DOWN: {
downX = event.getX();
return true;
}
case MotionEvent.ACTION_UP: {
upX = event.getX();
float deltaX = downX - upX;
// swipe horizontal?
if(Math.abs(deltaX) > MIN_DISTANCE){
// left or right
if(deltaX < 0) { this.onLeftToRightSwipe(); return true; }
if(deltaX > 0) { this.onRightToLeftSwipe(); return true; }
}
else {
Log.i(logTag, "Swipe was only " + Math.abs(deltaX) + " long, need at least " + MIN_DISTANCE);
return false; // We don't consume the event
}
return true;
}
}
return false;
}
}
Did you declare the set wallpaper permission in your AndroidManifest?
<uses-permission android:name="android.permission.SET_WALLPAPER" />
