获取当前屏幕分辨率的工具代码

直接新建个工程，放到主Activity的onCreate方法中即可。

?

/** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);//        setContentView(R.layout.main);                LinearLayout ll = new LinearLayout(this);        ll.setBackgroundColor(Color.GREEN);        TextView tv = new TextView(this);        tv.setTextSize(30);        tv.setTextColor(Color.RED);        LinearLayout.LayoutParams lll = new LinearLayout.LayoutParams(                LinearLayout.LayoutParams.WRAP_CONTENT,                LinearLayout.LayoutParams.WRAP_CONTENT        );                ll.addView(tv,lll);                DisplayMetrics dm= new DisplayMetrics();        this.getWindowManager().getDefaultDisplay().getMetrics(dm);        String solution = ""+dm.widthPixels+"*"+dm.heightPixels;        tv.setText("当前屏幕的分辨率是："+solution);                this.setContentView(ll);    }
