Android之Toast通知的几种自定义用法

Toast在手机屏幕上向用户显示一条信息，一段时间后信息会自动消失。

1.默认用法

[html] view plain copy

 print?

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

2.Fragment中的用法

[html] view plain copy

 print?

1. Toast.makeText(getActivity(),"网络连接错误，请检察网络设置", Toast.LENGTH_LONG).show();  

3.自定义显示位置效果

[html] view plain copy

 print?

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

4.带图片效果

[html] view plain copy

 print?

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 ImageView(getApplicationContext());  
5. imageCodeProject.setImageResource(R.drawable.icon);  
6. toastView.addView(imageCodeProject, 0);  
7. toast.show();  

5.完全自定义效果

[html] view plain copy

 print?

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 Toast(getApplicationContext());  
10. toast.setGravity(Gravity.RIGHT | Gravity.TOP, 12, 40);  
11. toast.setDuration(Toast.LENGTH_LONG);  
12. toast.setView(layout);  
13. toast.show();
