一个使用Fragement控件的简单实例

FirstFragement的建立

public class FirstFragement extends Fragment implements OnClickListener{
private Activity mActivity;
public ImageView image;
private OnBackgroundChangeListener onBackgroundChangeListener;

public void setOnBackgroundChangeListener(
OnBackgroundChangeListener onBackgroundChangeListener) {
this.onBackgroundChangeListener = onBackgroundChangeListener;
}

@Override
public void onAttach(Activity activity) {
mActivity=activity;
super.onAttach(activity);
}

@Override
public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {

View view=inflater.inflate(R.layout.first_fragement, null);
view.findViewById(R.id.fragebtn).setOnClickListener(this);
view.findViewById(R.id.changebtn).setOnClickListener(this);
image=(ImageView) view.findViewById(R.id.frageimage);
return view;
}

@Override
public void onClick(View v) {
switch(v.getId()){
case R.id.fragebtn:
image.setImageResource(R.drawable.b3);
break;
case R.id.changebtn:
this.onBackgroundChangeListener.onBackgroundChange();
break;
default:
break;
}

}

public interface OnBackgroundChangeListener{
public void onBackgroundChange();
}
