我main.xml在 android 上创建了一个窗口，在其中我有几个按钮，现在我创建了另一个Sound.xml窗口，那么如何在按下第一个窗口（main.xml）按钮时打开窗口。

在主 Java 上。

public class Main extends Activity {




@Override
protected void onCreate(Bundle savedInstanceState) {

   /** Called when the activity is first created. */

     super.onCreate(savedInstanceState);

     setContentView(R.layout.cyk_main);

     Button orderButton = (Button) findViewById(R.id.options_btn);
    orderButton.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            Intent intent = new Intent(Main.this,soundLayout.class);
            startActivity(intent);
        }
    });

在第二个窗口

public class soundLayout extends Activity {


@Override

  protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.soundLayout);
Button orderButton = (Button) findViewById(R.id.btn_finish_dialog);
orderButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
    finish();
}
});

}

<activity  
        android:name=".SoundOptionLayout
"android:theme="@android:style/Theme.Dialog" >
    </activity>

 <activity 
        android:name="com.myproject.testprojectonintent.ResultActivity"

        ></activity>

完成此工作后，我能够解决我的问题。
