官方NotePad实例学习--显式的Intent实例

显式的Intent通过指定组件的名称直接调用，一般是程序内部使用显式的方法。实例如下：

main.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" >


    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="跳转到其他Activity" />


</LinearLayout>

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.hebaijun.intenttest"
    android:versionCode="1"
    android:versionName="1.0" >


    <uses-sdk android:minSdkVersion="10" />


    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:label="@string/app_name"
            android:name=".IntentTestActivity" >
            <intent-filter >
                <action android:name="android.intent.action.MAIN" />


                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity 
            android:name=".OtherActivity"
            android:label="Other Activity">
        </activity>
    </application>


</manifest>

IntentTestActivity.java

package com.hebaijun.intenttest;


import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;


public class IntentTestActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Button button = (Button)findViewById(R.id.button1);
        button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(IntentTestActivity.this, OtherActivity.class);
startActivity(intent);
}
});
    }
}

OtherActivity.java

package com.hebaijun.intenttest;


import android.app.Activity;
import android.os.Bundle;


public class OtherActivity extends Activity{


@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
}
}

运行结果就不贴图了。
