如何让android上的吐司一直显示到用户触摸屏幕？

// 创建自定义的Toast布局
LayoutInflater inflater = getLayoutInflater();
View layout = inflater.inflate(R.layout.custom_toast, (ViewGroup) findViewById(R.id.custom_toast_container));
TextView text = layout.findViewById(R.id.custom_toast_text);
text.setText("Hello, Toast!");

// 创建Toast对象并设置自定义布局
Toast toast = new Toast(getApplicationContext());
toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0);
toast.setDuration(Toast.LENGTH_LONG);
toast.setView(layout);

// 显示Toast
toast.show();

// 创建透明的全屏幕Activity
Intent intent = new Intent(this, FullscreenActivity.class);
startActivity(intent);

@Override
public boolean dispatchTouchEvent(MotionEvent event) {
    // 判断用户是否触摸屏幕
    if (event.getAction() == MotionEvent.ACTION_DOWN) {
        // 关闭当前Activity
        finish();
        // 隐藏Toast
        toast.cancel();
        return true;
    }
    return super.dispatchTouchEvent(event);
}
