在畫廊上打開其他活動

Question

我有一個畫廊的圖像。我想在每次點擊圖庫中的圖像時打開其他活動。我很難與Onclicklisteners/onitemclicklisteners。

這是我的代碼。

public class MainActivity extends ActionBarActivity { 

private Integer[] pics = { R.drawable.school, R.drawable.gradeview, R.drawable.history, R.drawable.schoolorg }; 

private ImageView imageView; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 



    Gallery gallery = (Gallery) findViewById(R.id.gallery1); 
    gallery.setAdapter(new ImageAdapter(this)); 
    imageView = (ImageView) findViewById(R.id.imageView1); 
    gallery.setOnItemClickListener(new OnItemClickListener() { 

     @Override 
     public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, 
       long arg3) { 
      // TODO Auto-generated method stub 

      // 
      // I DON'T KNOW WHAT TO PUT HERE 
      // I DON'T KNOW WHAT TO PUT HERE 

     } 
    }); 

} 

@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; 
} 
public class ImageAdapter extends BaseAdapter{ 
    private Context context; 
    int imageBackground; 

    public ImageAdapter(Context context){ 
     this.context = context; 
    } 

    @Override 
    public int getCount() { 
     // TODO Auto-generated method stub 
     return pics.length; 
    } 

    @Override 
    public Object getItem(int arg0) { 
     // TODO Auto-generated method stub 
     return arg0; 
    } 

    @Override 
    public long getItemId(int arg0) { 
     // TODO Auto-generated method stub 
     return arg0; 
    } 

    @Override 
    public View getView(int arg0, View arg1, ViewGroup arg2) { 
     // TODO Auto-generated method stub 
     ImageView imageView = new ImageView(context); 
     imageView.setImageResource(pics[arg0]); 
     return imageView; 
    } 
} 

}

Answer 1

打開其他活動，你可以的simpy用戶意圖，

Intent intent = new Intent(); 
intent.setClass(getApplicationContext(), YOUR_NEW_ACTIVITY.class); 
startActivity(intent); 

但要肯定的是，新的活動都必須在明顯的類似聲明：

<activity android:name=".YOUR_NEW_ACTIVITY"></activity> 

Answer 2

gallery.setOnItemClickListener(new OnItemClickListener() { 

     @Override 
     public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, 
       long arg3) { 
      // TODO Auto-generated method stub 

      Intent intent =new Intent(MainActvity.this,ImageShow.class);//Class name to redirect 
intent.putExtra("Image",pics[arg2]); //Image url to send to the next to show image 
startActivity(intent); 
this.finish(); 


     } 
    });
