先写个布局文件

activity_main.xml

 1 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 2     xmlns:tools="http://schemas.android.com/tools"
 3     android:layout_width="match_parent"
 4     android:layout_height="match_parent"
 5     android:orientation="vertical"
 6     android:gravity="center_horizontal"
 7     >
 8 
 9     <Button 
10         android:id="@+id/btn1"
11         android:layout_width="wrap_content"
12         android:layout_height="wrap_content"
13         android:text="版权声明" />
14     <Button 
15         android:id="@+id/btn2"
16         android:layout_width="wrap_content"
17         android:layout_height="wrap_content"
18         android:text="这是我自定义的toast" />
19     
20 
21 </LinearLayout>

toast.xml

 1 <?xml version="1.0" encoding="utf-8"?>
 2 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 3     android:layout_width="match_parent"
 4     android:layout_height="wrap_content"
 5     android:orientation="horizontal" >
 6     
 7    <ImageView 
 8        android:id="@+id/img"
 9        android:layout_width="wrap_content"
10        android:layout_height="wrap_content"
11        android:src="@drawable/ic_launcher"
12        />
13 
14    <TextView 
15        android:id="@+id/tv"
16        android:layout_width="match_parent"
17        android:layout_height="wrap_content"
18        android:textSize="30sp"
19        android:text="自定义的Toast"
20        />
21 </LinearLayout>
MainActivity中的代码

import android.widget.Toast;



 1 public class MainActivity extends Activity {
 2 
 3     private Button btn1;
 4     private Button btn2;
 5 
 6     @Override
 7     protected void onCreate(Bundle savedInstanceState) {
 8         super.onCreate(savedInstanceState);
 9         setContentView(R.layout.activity_main);
10         btn1 = (Button) findViewById(R.id.btn1);
11         btn2 = (Button) findViewById(R.id.btn2);
12         接受和拒绝();
13         自定义Toast();
14     }
15 
16     private void 自定义Toast() {
17         btn2.setOnClickListener(new View.OnClickListener() {
18             @Override
19             public void onClick(View arg0) {
20                 Context ct = MainActivity.this;// 上下文
21                 Toast toast = new Toast(ct);// 创建Toast对象
22                 LayoutInflater jj = getLayoutInflater();// 渲染器
23                 View zz = jj.inflate(R.layout.toast, null);// 渲染成一个View视图
24                 TextView gg = (TextView) zz.findViewById(R.id.tv);// 用来显示
25                 toast.setView(zz);//
26                 toast.setDuration(10);// 显示时间
27                 toast.show();// 展示
28             }
29         });
30     }
31 
32     private void 接受和拒绝() {
33         btn1.setOnClickListener(new View.OnClickListener() {
34 
35             @Override
36             public void onClick(View arg0) {
37                 AlertDialog.Builder builder = new Builder(MainActivity.this);
38 
39                 builder.setTitle("版权声明");
40                 builder.setIcon(R.drawable.ic_launcher);
41                 builder.setMessage("该原生对话框有Google开发，版权所有，违者必究");
42                 builder.setNegativeButton("拒绝", new OnClickListener() {
43                     @Override
44                     public void onClick(DialogInterface arg0, int arg1) {
45                         // TODO Auto-generated method stub
46                         Toast.makeText(getApplicationContext(), "我拒绝",
47                                 Toast.LENGTH_SHORT).show();
48 
49                     }
50                 });
51                 builder.setPositiveButton("接受", new OnClickListener() {
52 
53                     @Override
54                     public void onClick(DialogInterface arg0, int arg1) {
55                         Toast.makeText(getApplicationContext(), "我已阅读，同意",
56                                 Toast.LENGTH_SHORT).show();
57                     }
58                 });
59                 builder.setCancelable(false);
60                 AlertDialog arg01 = builder.show();
61             }
