Android获取屏幕宽高像素

public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); DisplayMetrics metrics = new DisplayMetrics(); //给当前metrics去设置当前屏幕信息(宽高(像素单位)) getWindowManager().getDefaultDisplay().getMetrics(metrics); //获取屏幕的宽度和高度 int widthPixels = metrics.widthPixels; int heightPixels = metrics.heightPixels; Toast.makeText(this, "宽" + widthPixels + ",高" + heightPixels, Toast.LENGTH_SHORT).show(); } }
