今天做android开发一个小项目怎么都调不通，然后就随便建了个测试用例，发现startActivity函数竟然总是出错，我已经在AndroidManifest.xml 对新建的页面进行的注册了，但是依然不行不知道是什么原因，现在贴出来代码请大家指教！
Activity01代码
package An.Android;
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 TestA extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button to_anoter = (Button) findViewById(R.id.button1); //测试打开新的activity
to_anoter.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
// TODO Auto-generated method stub
Intent intent0 = new Intent(TestA.this,anotherActivity.class);
setTitle("test");
startActivity(intent0);
TestA.this.finish();
//CityWeather.this.finish();
}
});
}
}
对应的mian.xml文件如下
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello"
/>
<Button android:text="试试" android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
</LinearLayout>
Activity02的代码如下：
package An.Android;
import android.app.Activity;
import android.os.Bundle;
public class anotherActivity extends Activity{
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.another);
};
}
对应的xml文件如下：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="你好啊！"
/>
</LinearLayout>
AndroidManifest.xml 对应如下：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="An.Android"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".TestA"
android:label="@string/app_name">
