使用包含自定义动作的隐式Intent

1、activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

<Button
android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="转到下一个Activity"
android:textColor="@android:color/black"/>

</LinearLayout>

2、secondactivity_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<TextView
android:id="@+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="第二个Activity"
android:textColor="@android:color/black"
android:textSize="25px" />

</LinearLayout>

3、MainActivity.java

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button = (Button)findViewById(R.id.button);
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent();
intent.setAction("");//为Intent设置动作
startActivity(intent);
}
});
}
}

4、SecondActivity.java

public class SecondActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.secondactivity_layout);
}
}

5、AndroidManifest.xml配置文件，为两个Activity设置不同的Intent过滤器

<activity
android:name="com.example.android6_3.MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".SecondActivity">
<intent-filter>
<action android:name="<span style="font-family: Arial, Helvetica, sans-serif;">test_action</span>"/>
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</activity>
