 8         btnJump.setOnClickListener(new View.OnClickListener() {
 9             @Override
10             public void onClick(View view) {
11                 //显式跳转方法1
12                 Intent intent=new Intent(AActivity.this,BActivity.class);
13                 startActivity(intent);
14
15                 //显式跳转方法二
16                 //Intent intent=new Intent();
17                 //intent.setClass(AActivity.this,BActivity.class);
18                 //startActivity(intent);

20                 //显示跳转方法三
21                 //Intent intent=new Intent();
22                 //intent.setClassName(AActivity.this, "com.example.first.jump.BActivity");
23                 //startActivity(intent);
24
25                 //显式跳转方法四
26                 //Intent intent=new Intent();
27                 //intent.setComponent(new ComponentName(AActivity.this, "com.example.first.jump.BActivity"));
28                 //startActivity(intent);

30                 //隐式跳转
31                 //Intent intent=new Intent();
32                 //intent.setAction("com.example.test.BActivity");
33                 //startActivity(intent);
34                 //隐式跳转需要在AndroidMainifest.xml文件中要跳转的activity下设置<intent-filter>标签，像这样
35                 /*<intent-filter>
36                     <action android:name="com.example.test.BActivity" />
