android tv box launcher开发之添加自定义apk

在开发launcher中通常有这个需求就是在主界面上预留空白控件，可以让用户从apps中自己选择apk放入。
1.   点击空白控件跳转到选择apk的布局中，所以我们需要写一个布局用来存放所有的apk，这里我使用的是activity，当然也可以用framlayout。

public class Test extends Activity implements AdapterView.OnItemClickListener{
   
   
    private GridView gv;
    private final static String TAG = "Test";
    private final static String NAME = "item_name";
    private final static String ICON = "item_icon";
    private final static String SELECTION = "item_selection";
    private final static String BACKGROUND = "item_background";
    private final static String COMPONENT_NAME = "component name";

    private final static int duration = 300;

    private ImageView img_screen_shot = null;
    private ImageView img_screen_shot_keep = null;
    private ImageView img_dim = null;

    private CustomView thisView = null;
    private Context mContext = null;

    private String[] list_custom_apps;
    private String str_custom_apps;
    private Drawable bitmap;
    private String str_name; 

    private int transY = 0;
    private int homeShortcutCount;

    final static Object mLock = new Object[0];
    private View mSource;
    private int mMode = -1;
    private int mPos = -1;
    private int resultCode = 3;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_custom_apps);
    mContext = Launcher.context;
        mMode = 4;
    gv =(GridView) findViewById(R.id.grid_add_apps);
        gv.setOnItemClickListener(this);
    displayView();
    }

    @Override
    protected void onPause() {
    super.onPause();
    }

    @Override
    protected void onStop() {
    Log.d(TAG,"onStop---------------onStop");
        super.onStop();
    }

    @Override
    protected void onDestroy() {
    Log.d(TAG,"onDestroy---------------onDestroy"+str_custom_apps);
        super.onDestroy();
    }
    /*
    * press down key sendBroadcast back launcher.java and send packageName
    */
    public boolean dispatchKeyEvent (KeyEvent event) {
        if (event.getAction() == KeyEvent.ACTION_DOWN) {
            switch (event.getKeyCode()) {
                case KeyEvent.KEYCODE_BACK:
                    Intent intent = new Intent();
            intent.putExtra("pkg",str_custom_apps);
                intent.setAction("com.ff.pkg");
                this.sendBroadcast(intent);
                    Log.d(TAG, "KeyEvent.KEYCODE_BACK............");
                    break;
            }
        }

        return super.dispatchKeyEvent(event);
    }
