Android Toast实现全屏显示

private void toastFullScreen(){
 Toast toast = Toast.makeText(this, null, Toast.LENGTH_LONG * 10 * 1000);
 toast.setGravity(Gravity.CENTER, 0, 0);
 LinearLayout toastView = (LinearLayout)toast.getView();
 
 // Get the screen size with unit pixels.
 WindowManager wm = (WindowManager)getSystemService(Context.WINDOW_SERVICE);
 DisplayMetrics outMetrics = new DisplayMetrics();
 wm.getDefaultDisplay().getMetrics(outMetrics);
 
 TextView tv = new TextView(this);
 LayoutParams vlp = new LayoutParams(outMetrics.widthPixels,
               outMetrics.heightPixels); 
 vlp.setMargins(0, 0, 0, 0);
 tv.setLayoutParams(vlp);
 tv.setText("Hello Toast! I am full screen now.");
 tv.setGravity(Gravity.CENTER);
 
 toastView.addView(tv);
 toast.show();
}

public class MyToast {

  private static Toast mGoodToast;
  private static ObjectAnimator mObjectAnimator;

  public static void showGoodToast(Context context) {

    if (mGoodToast == null) {
      mGoodToast = new Toast(context);
      mGoodToast.setGravity(Gravity.CENTER, 0, 0);
      mGoodToast.setDuration(Toast.LENGTH_LONG);
      View view = LayoutInflater.from(context).inflate(R.layout.dialog_good, null, false);
      AppCompatImageView imageView = view.findViewById(R.id.shine);
      mObjectAnimator = ObjectAnimator.ofFloat(imageView, "rotation", 5000);
      mObjectAnimator.setInterpolator(new LinearInterpolator());
      mObjectAnimator.setDuration(30000);
      mGoodToast.setGravity(Gravity.FILL, 0, 0);
      mGoodToast.setView(view);
      mGoodToast.getView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);//设置Toast可以布局到系统状态栏的下面
    }
