Question

我正在实现可滑动的标签。我有3个标签。在最后一个标签中有4个按钮，点击后会启动另一个片段活动。但是当我点击第二个标签中的可用空间时，同样的onclick就会被触发。请帮助我这是真的。

以下是我的补充项目链接https://drive.google.com/file/d/0B3znk-VNWY6RUHVvdDBpNWlmN3M

AlbumsFragment

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.Toast;

public class AlbumsFragment extends Fragment implements OnClickListener {

    View view;
    Button albums,songs,artists,playlist;
    Activity thisActivity;
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        view=inflater.inflate(R.layout.fragment_albums, container,false);
        thisActivity=getActivity();
        albums=(Button) view.findViewById(R.id.btn_albums);
        songs=(Button) view.findViewById(R.id.btn_allsongs);
        artists=(Button) view.findViewById(R.id.btn_artists);
        playlist=(Button) view.findViewById(R.id.btn_playlist);
        albums.setOnClickListener(AlbumsFragment.this);
        songs.setOnClickListener(AlbumsFragment.this);
        artists.setOnClickListener(AlbumsFragment.this);
        playlist.setOnClickListener(AlbumsFragment.this);

        return view;
    }


    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        switch (v.getId()) {
        case R.id.btn_albums:

            Toast.makeText(thisActivity, "in", 100).show();
            Intent i=new Intent(thisActivity,PlayList.class);
            thisActivity.startActivity(i);
            thisActivity.overridePendingTransition(R.anim.flip_left_to_right, R.anim.flip_right_to_left);


            break;

        default:
            break;
        }

    }

}

这个onclicklistener在相邻的片段中被解雇了。

public class RecordFragment extends Fragment {

    View view;
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        view=inflater.inflate(R.layout.fragment_audio_recorder, container, false);

        return view;
    }



}

为不可见的片段禁用onClick方法。为此，请添加此代码 -

if(!getUserVisibleHint())
{return false;}

在每个片段的第一行OnClick方法之前，如果片段不可见，则不会执行OnClick方法。

片段的OnClickListener也会在另一个片段中被触发
