Toast用于向用户显示一些帮助/提示。下面我做了5中效果，来说明Toast的强大，定义一个属于你自己的Toast。

1.默认效果

代码

Toast.makeText(getApplicationContext(), "默认Toast样式",
Toast.LENGTH_SHORT).show();

2.自定义显示位置效果

代码

toast = Toast.makeText(getApplicationContext(),
     "自定义位置Toast", Toast.LENGTH_LONG);
   toast.setGravity(Gravity.CENTER, 0, 0);
   toast.show();

3.带图片效果

代码

toast = Toast.makeText(getApplicationContext(),
     "带图片的Toast", Toast.LENGTH_LONG);
   toast.setGravity(Gravity.CENTER, 0, 0);
   LinearLayout toastView = (LinearLayout) toast.getView();
   ImageView imageCodeProject = new ImageView(getApplicationContext());
   imageCodeProject.setImageResource(R.drawable.icon);
   toastView.addView(imageCodeProject, 0);
   toast.show();

4.完全自定义效果

代码

LayoutInflater inflater = getLayoutInflater();
   View layout = inflater.inflate(R.layout.custom,
     (ViewGroup) findViewById(R.id.llToast));
   ImageView image = (ImageView) layout
     .findViewById(R.id.tvImageToast);
   image.setImageResource(R.drawable.icon);
   TextView title = (TextView) layout.findViewById(R.id.tvTitleToast);
   title.setText("Attention");
   TextView text = (TextView) layout.findViewById(R.id.tvTextToast);
   text.setText("完全自定义Toast");
   toast = new Toast(getApplicationContext());
   toast.setGravity(Gravity.RIGHT | Gravity.TOP, 12, 40);
   toast.setDuration(Toast.LENGTH_LONG);
   toast.setView(layout);
   toast.show();

5.其他线程

代码

new Thread(new Runnable() {
    public void run() {
     showToast();
    }
   }).start();

主

public void showToast() {
handler.post(new Runnable() {

   @Override
   public void run() {
    Toast.makeText(getApplicationContext(), "我来自其他线程！",
      Toast.LENGTH_SHORT).show();

}
});
}
