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

     ”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

    public void run() \{  
     showToast();  
    \}  
   \}).start();
