如何在Android的永久设置壁纸 [英] How to set wallpaper permanently in android

问题描述

我创建的应用程序可以设置图像为墙纸。我使用以下code固定在每一个屏幕图像。在code是工作的罚款。图像适应正常。但我有一个问题，如果我玩任何游戏，然后返回到主屏幕或重新启动设备，然后壁纸变焦的大小。我想阻止这一切。我想图像大小适合，因为它是当我设置从我的Andr​​oid应用程序的墙纸第一次。

I am creating app to set image as wallpaper. I am using following code to fix image in every screen. The code is working fine. Image fit properly. But I have one problem if I play any game and then back to home screen or I restart my device then size of wallpaper zoom. I want to stop this. I want image size fit as it is on first time when I set wallpaper from my android app.

下面是code -

Here's Code-

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.full_image);
        face = Typeface.createFromAsset(getAssets(), "fonts/ABEAKRG.TTF");
        Intent i = getIntent();
        position = i.getExtras().getInt("id");        
        full = (LinearLayout) findViewById(R.id.full);
        btn = (Button)findViewById(R.id.btn);
        btn.setTypeface(face);
        btn.setOnClickListener(new Button.OnClickListener(){
        @Override
        public void onClick(View arg0) { 
             DisplayMetrics metrics = new DisplayMetrics(); 
             getWindowManager().getDefaultDisplay().getMetrics(metrics);
             int height = metrics.heightPixels; 
             int width = metrics.widthPixels;
             Bitmap tempbitMap = BitmapFactory.decodeResource(getResources(), mThumbId[position]);
             Bitmap bitmap = Bitmap.createScaledBitmap(tempbitMap,width,height, true);
             WallpaperManager wallpaperManager = WallpaperManager.getInstance(FullImageActivity.this); 
             wallpaperManager.setWallpaperOffsetSteps(1, 1);
             wallpaperManager.suggestDesiredDimensions(width, height);
             try {
               wallpaperManager.setBitmap(bitmap);
               Toast.makeText(getApplicationContext(), "Done", Toast.LENGTH_SHORT).show();
               } catch (IOException e) {
               e.printStackTrace();
             }
        }});
        changeBackground();
        ActivitySwipeDetector activitySwipeDetector = new ActivitySwipeDetector(this);
        full.setOnTouchListener(activitySwipeDetector);
    }



    private void changeBackground(){
        full.setBackgroundResource(mThumbId[position]);
   }

先谢谢了。
