按下button 1 之后 进入secondactivity活动
2建立一个新的活动
(1)建立一个新的布局文件second.xml,在res/layout文件中
建议如下代码活动(一个Button)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<span style="color:#FF0000;"> <Button
android:id="@+id/button_2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Button 2"
/>
</span>
</LinearLayout>
(2)在src中建立新的java,建立新的活动SecondActivity继承Activity
package com.example.activitytest;
import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
public class SecondActivity <span style="color:#FF0000;">extends Activity</span>{
<span style="color:#FF0000;">@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.second);</span>
}
}
(3)最后在菜单文件中为SecondActivity进行注册
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".FirstActivity"
android:label="This is FirstActivity"
>
<intent-filter >
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<span style="color:#FF0000;"> <activity android:name=".SecondActivity">
</activity></span>
</application>
(4)修改FirstActivity按钮的点击事件
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();
<span style="color:#FF0000;">Intent intent = new Intent(FirstActivity.this,SecondActivity.class);
startActivity(intent);</span>
}
});
}
这样就可以用第一个活动来启动第二个活动!!!
