获取手机分辨率
 private TextView textView;
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);
  DisplayMetrics displayMetrics = new DisplayMetrics();
  getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
  String string = "手机屏幕分辨率为：" + displayMetrics.widthPixels + "x" + displayMetrics.heightPixels;
  textView = (TextView) findViewById(R.id.textView);
  textView.setText(string);
 }

 Application用于获取一些全局数据，各种Activity,Adapter，View等都可用的数据，使用时一般创建MyApplication子类，

调用时用Activity的getApplication方法，

(MyApplication)getApplication.killPrice(str)

在View中：
((MyApplication)getContext().getApplicationContext()).getScore()
