android点击layout跳转,最简单的Activity跳转

使用Intent进行最简单的Activity跳转，不传递数据也不返回数据的！点击Activity1的按扭跳转到Activity2，点击Activity2的按钮返回Activity1。

1、Activity1和Activity2的xml界面，都只包含一个TextView和一个Button

http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:orientation="vertical">

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="@string/activity1_text" />

android:id="@+id/btn1"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="跳转到Avtivity2"/>

http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:orientation="vertical" >

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="@string/activity2_text" />

android:id="@+id/btn2"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="返回Activity1"/>

2、Java代码：

public class MainActivity extends Activity {

private Button Btn1 = null;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

Btn1 = (Button)findViewById(R.id.btn1);

Btn1.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

Intent intent = new Intent(MainActivity.this, MyActivity.class);  //跳转到Activity2

startActivity(intent);

}

});

}

}

public class MyActivity extends Activity {

private Button Btn2 = null;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity2_layout);

Btn2 = (Button)findViewById(R.id.btn2);

Btn2.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

Intent intent = new Intent(MyActivity.this, MainActivity.class);//返回Activity1

startActivity(intent);

}

});

}

}

3、配置AndroidManifest.xml,配置新添加的Activity

android:name="com.czh.toactivity.MyActivity"

android:label="@string/app_name" >

4、运行结果：
