废话不说，直接上代码：

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();

}根据实际情况，在toastView添加不同view能显示不同弹窗，希望对大家有帮助！
