Android学习 之 获取手机屏幕像素

有三种方法，其实都是一样的，只是做了不同的封装：

?

private void getPhoneDisplayInfo(){    // 1.    DisplayMetrics displayMetrics1 = new DisplayMetrics();    getWindowManager().getDefaultDisplay().getMetrics(displayMetrics1);    int screenWidth = displayMetrics1.widthPixels;    int screenHeight = displayMetrics1.heightPixels;    Log.d("debug", "screenWidth = "+screenWidth+"|screenHeight = "+screenHeight);        // 2.    DisplayMetrics displayMetrics2 = new DisplayMetrics();    displayMetrics2 = getApplicationContext().getResources().getDisplayMetrics();    Log.d("debug", "screenWidth = "+displayMetrics2.widthPixels+"|screenHeight = "+displayMetrics2.heightPixels);        // 3.    Display display = getWindowManager().getDefaultDisplay();    Log.d("debug", "screenWidth = "+display.getWidth()+"|screenHeight = "+display.getHeight());        }
