连接活动

Question

有人可以告诉我，我错了。我有三个活动，我想连接togever。这段代码是我的第一个java文件和第一个xml文件。我认为我的onclick代码在某些地方不对。我的最终结果是所有3个活动连接3个图像按钮...谢谢

java 1.code 包my.hope;

    import android.app.Activity;
    import android.os.Bundle;
    import android.view.View;
    import android.view.View.OnClickListener;
    import android.widget.ImageView;
    import android.content.Intent;
    public class NewhopeActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    ImageView myImage = (ImageView) findViewById(R.id.imageButton1);
    myImage.setOnClickListener(new OnClickListener() {

        intent intent = new intent(Newhopeactivity.this, Act2.class);
        startActivity(intent);

            public void onClick(View v) {
                // TODO Auto-generated method stub

            }
    }  
  );  
} 

}

xml.code

    <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <TextView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/hello" />

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/bt" />

<ImageButton
    android:id="@id/imageButton1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/ic_launcher" 
    android:onClick="Act2"/>

Answer 1

您必须将startActivity（）放入实际的onClick（）方法中。

myImage.setOnClickListener(new OnClickListener() {


        public void onClick(View v) {
            intent intent = new intent(Newhopeactivity.this, Act2.class);
            startActivity(intent);
        }
}  

Answer 2

更改

ImageView myImage = (ImageView) findViewById(R.id.imageButton1);
myImage.setOnClickListener(new OnClickListener() {

    intent intent = new intent(Newhopeactivity.this, Act2.class);
    startActivity(intent);

        public void onClick(View v) {
            // TODO Auto-generated method stub

        }
}

到

ImageView myImage = (ImageView) findViewById(R.id.imageButton1);
myImage.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {
            // TODO Auto-generated method stub          
            Intent intent = new intent(Newhopeactivity.this, Act2.class);
            startActivity(intent);
        }
}
