Question

这是我的滑动片段的java代码，我在该片段中做了一个布局，我想让“正在进行的”RelativeLayout可点击以导航到其他活动。请帮我解决这个问题。

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.ViewGroup;
import android.view.View.OnClickListener;
import android.widget.LinearLayout;
import android.widget.RelativeLayout;
import android.widget.TextView;
import info.androidhive.CrescentBuilders.R;

public class Ongoing extends Fragment {
  @Override
      public View onCreateView(LayoutInflater inflater, ViewGroup container,
              Bundle savedInstanceState) {
           View android = inflater.inflate(R.layout.ongoing_frag, container, false);
          //((TextView)android.findViewById(R.id.textView)).setText("Ongoing Projects");
          RelativeLayout ongoing=(RelativeLayout)android.findViewById(R.id.layoutongoing);
           return android;



}


}

如果布局在片段

中，您应该在onViewCreated而不是onCreateView中找到Id

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

       View android = inflater.inflate(R.layout.ongoing_frag, container, false);

       return android;
   }

  @Override
  public void onViewCreated(View view, Bundle savedInstanceState) {

       RelativeLayout ongoing=(RelativeLayout)view.findViewById(R.id.layoutongoing);
   }

如何在Fragment中制作可点击的布局
