Android Toast实现提示效果

Toast.makeText(MainActivity.this, "Toast testing.", Toast.LENGTH_LONG).show();

/*设置ImageView*/
ImageView imageView=new ImageView(MainActivity.this);
imageView.setImageResource(R.drawable.ic_launcher);
/*以Toast方式显示*/
Toast toast=Toast.makeText(MainActivity.this, "Toast testing", Toast.LENGTH_LONG);
/*设置Toast对象在手机的相对位置*/
toast.setGravity(Gravity.BOTTOM, 0, 0);
/*用getView的方法将Toast转化为LinearLayout，然后将ImageView添加到文字前面*/
LinearLayout toastViewLayout =(LinearLayout)toast.getView();
toastViewLayout.addView(imageView, 0);
/*显示Toast*/
toast.show();
