代码:
修改菜单文件中的SecondActivity
<activity android:name=".SecondActivity">
<intent-filter>
<action android:name="com.example.activitytest.Action_START"/>
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</activity>
满足activity与category事件响应
将FirstActivity中的响应事件代码修改
Button button1 = (Button) findViewById(R.id.button_1);
button1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
//Toast .makeText(FirstActivity .this, "you click the button 1", Toast.LENGTH_SHORT).show();
Intent intent = new Intent("com.example.activitytest.Action_START");
startActivity(intent);
}
});
每个Intent只能有一个action,但可以有多个category
下面在增加一个category
在FirstActivity中修改按钮响应
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
//Toast .makeText(FirstActivity .this, "you click the button 1", Toast.LENGTH_SHORT).show();
Intent intent = new Intent("com.example.activitytest.Action_START");
intent.addCategory("com.example.activitytest.MY_CATEGORY");
startActivity(intent);
}
在菜单文件中加入对应category\
<activity android:name=".SecondActivity">
<intent-filter>
<action android:name="com.example.activitytest.Action_START"/>
<category android:name="android.intent.category.DEFAULT"/>
<category android:name="com.example.activitytest.MY_CATEGORY"/>
</intent-filter>
</activity>
