在android中设置Wallpaer

Question

我想构建一个简单的壁纸应用程序，但只是无法设置壁纸。我已经尝试了很多方法，但却无法理解如何实现wallpapermanager。

final LinearLayout L1 = (LinearLayout) findViewById(R.id.l1);
final ImageView I1 = (ImageView) findViewById(R.id.imageView);
ImageView I2 = (ImageView) findViewById(R.id.imageView2);
ImageView I3 = (ImageView) findViewById(R.id.imageView3);
ImageView I4 = (ImageView) findViewById(R.id.imageView4);
ImageView I5 = (ImageView) findViewById(R.id.imageView5);
ImageView I6 = (ImageView) findViewById(R.id.imageView6);
ImageView I7 = (ImageView) findViewById(R.id.imageView7);
ImageView I8 = (ImageView) findViewById(R.id.imageView8);
ImageView I9 = (ImageView) findViewById(R.id.imageView9);
ImageView I10 = (ImageView) findViewById(R.id.imageView10);
ImageView I11 = (ImageView) findViewById(R.id.imageView11);
ImageView I12 = (ImageView) findViewById(R.id.imageView12);
ImageView I13 = (ImageView) findViewById(R.id.imageView13);
ImageView I14 = (ImageView) findViewById(R.id.imageView14);
Button b1 = (Button) findViewById(R.id.button);
final WallpaperManager my = WallpaperManager.getInstance(getApplicationContext());

I1.setOnClickListener(new ImageView.OnClickListener() {
                          @Override
                          public void onClick(View v) {
                              {
                                      /*abc = 1;
                                      if(abc==1) {
                                          L1.setVisibility(View.GONE);
                                          abc = 0;
                                      }*/

                              }
