遇到错误code在这里活动片段

问题描述

这是我的活动课code ...我想点击的ImageButton并启动片段类，但问题是我在这行上了code误差

This is my Activity Class code... i want to click the imagebutton and launch the fragment class, but the problem is i got error on the code in this line

BluActivity f = BluActivity.newInstance(index);
getSupportFragmentManager().beginTransaction().add(R.id.detail, f).commit();

我附上图片看到什么我的关于它的问题:( ...

import android.widget.ImageButton;
public class MainActivity extends Activity {
public static final String INDEX = "index";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    setupImageButton1();
}

private void setupImageButton1(){
    ImageButton imgButton = (ImageButton) findViewById(R.id.bataImg2);
    imgButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
        // TODO Auto-generated method stub
        Intent i = getIntent();
        int index = i.getIntExtra(INDEX, 0);
        BluActivity f = BluActivity.newInstance(index);
        getSupportFragmentManager().beginTransaction().add(R.id.detail, f).commit();
        }
    });
    setupImageButton1();
}

    private void setupImageButton3(){
    ImageButton imgButton = (ImageButton) findViewById(R.id.bataImg1);
    imgButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            finish();
            }
        });
    }
}

**这里是我的错误形象附加

这里是bluactivity类

here is the bluactivity class

推荐答案

您BluActivity类似乎并不延伸片段。

Your BluActivity class doesn't seems to extend Fragment.

变化与扩展，以分片和相关的变化

Change and extend it to Fragment and related changes
