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() {@Overridepublic 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 {@Overrideprotected 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>
