android获取屏幕分辨率的两种方法

WindowManager windowManager = getWindowManager();

Display display = windowManager.getDefaultDisplay();

int screenWidth = screenWidth = display.getWidth();

int screenHeight = screenHeight = display.getHeight();

// 方法2

DisplayMetrics dm = new DisplayMetrics();

getWindowManager().getDefaultDisplay().getMetrics(dm);

//TextView tv = (TextView)this.findViewById(R.id.);

float width=dm.widthPixels*dm.density;

float height=dm.heightPixels*dm.density;

TextView tv=(TextView) this.findViewById(R.id.tv);

tv.setText("First method:"+dm.toString()+"\n"+"Second method:"+"Y="+screenWidth+";X="+screenHeight);
