1：无返回结果的页面跳转
1>新建一个Activity文件如MainActivity；重写onCreat方法；设置xml文件关联，setContentView(R.layout.activity_main)；
2>新建xml文件如activity_main.xml；在里面设置控件
3>新建一个Activity文件如Second_Activity；重写onCreat方法；设置xml文件关联，setContentView(R.layout.secondview)；
4>新建xml文件如secondview.xml；在里面设置控件
5>将新建的Activity文件都配置到Android.Manifest.xml文件中
6>重写第一个页面跳转到第二个页面的按钮的点击事件的方法
Intent intent = new Intent(MainActivity.this,SecondActivity.class);//第一个参数是上下文文件，第二个对象是目标文件
MainActivity.this.startActivity(intent);
1>MainActivity.java
package com.thinker.activitydemo; import android.app.Activity; import android.content.Intent; import android.content.IntentFilter; import android.os.Bundle; import android.view.Menu; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; public class MainActivity extends Activity { private Button btn; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); btn = (Button) findViewById(R.id.button1); btn.setOnClickListener(new OnClickListener() { @Override public void onClick(View arg0) { // TODO Auto-generated method stub Intent intent = new Intent(MainActivity.this,Second_Activity.class); MainActivity.this.startActivity(intent); } }); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } }
2〉activity_main.xml
<RelativeLayout 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:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context=".MainActivity" > <Button android:id="@+id/button1" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:text="启动第二个Activity" /> </RelativeLayout>
3〉Second_Activity.java
package com.thinker.activitydemo; import android.app.Activity; import android.os.Bundle; import android.widget.Button; public class Second_Activity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.secondview); } }
4:secondview.xml
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" > <TextView android:id="@+id/textView1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_centerHorizontal="true" android:layout_marginTop="67dp" android:text="这是第二个Activity" /> </RelativeLayout>
5：AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.thinker.caculator" android:versionCode="1" android:versionName="1.0" > <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="18" /> <application android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <activity android:name="com.thinker.caculator.MainActivity" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name="com.thinker.caculator.SecondActivity" ></activity> </application> </manifest>
