是的,我知道此问题之前已被问过几十次。但是,在实施多个解决方案时,我的应用程序强制关闭。我试过点按一下按钮:
//Determine Screen Size and Create Layout Param
android.view.Display display = ((android.view.WindowManager)getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
int BtnWth = display.getWidth() / 4;
int BtnHgt = display.getHeight() / 4;
RelativeLayout.LayoutParams BtnDim = new RelativeLayout.LayoutParams(BtnWth, BtnHgt);
// Declare MPC pads
Button pad1 = (Button) findViewById(R.id.pad1);
public void onClick(){
// Set width and height of each pad
pad1.setLayoutParams(BtnDim);
}
还使用onDraw()方法。两者都强行关闭真正的Android 3.1设备。

尝试使用此代码来获取屏幕宽度和高度(以像素为单位):
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
int screenWidth = dm.widthPixels;
int screenHeight = dm.heightPixels;
确保将其添加到导入中:
import android.util.DisplayMetrics;
