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

 

Java代码  

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

2.自定义显示位置效果

Java代码  

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

 

3.带图片效果

Java代码  

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

 

4.完全自定义效果

Java代码  

 
    
  
1. LayoutInflater inflater = getLayoutInflater();  
2. View layout = inflater.inflate(R.layout.custom,(ViewGroup) findViewById(R.id.llToast));  
3. ImageView image = (ImageView) layout.findViewById(R.id.tvImageToast);  
4. image.setImageResource(R.drawable.icon);  
5. TextView title = (TextView) layout.findViewById(R.id.tvTitleToast);  
6. title.setText("Attention");  
7. TextView text = (TextView) layout.findViewById(R.id.tvTextToast);  
8. text.setText("完全自定义Toast");  
9. toast = new
10. toast.setGravity(Gravity.RIGHT | Gravity.TOP, 12, 40);  
11. toast.setDuration(Toast.LENGTH_LONG);  
12. toast.setView(layout);  
13. toast.show();

5.其他线程

Java代码 

 
    
  
1. new Thread(new
2. public void
3.        showToast();  
4.     }  
5. }).start();
