Question

我已经创建了ButtonFragment类，我们在其中实现了按钮单击视图上的方法并标识特定按钮，何时我们点击按钮事件会起作用，但是当我们尝试打开时像startActivity方法这样的另一个活动给出了错误。我们怎么能这样做，谁能帮我。以下是我的代码。

   package com.viewpagerex;



import android.content.Context; import android.content.Intent;
import android.os.Bundle; import android.support.v4.app.Fragment;
import android.util.Log; import android.view.LayoutInflater; import
android.view.View; import android.view.View.OnClickListener; import
android.view.ViewGroup; import android.widget.ImageButton;




public class ButtonFragment extends Fragment implements  OnClickListener 
{ 

private static final String TAG = null;
    protected static final Context context=null;

    public void onCreate(Bundle savedInstanceState)
{
        super.onCreate(savedInstanceState);
    Log.e(TAG,"HelloHelooooo");

    }   
public void onActivityCreated(Bundle savedInstanceState) 
{       super.onActivityCreated(savedInstanceState);

   }    

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

        View view = inflater.inflate(R.layout.button, container, false);    

  ImageButton imgBtn = (ImageButton)  view.findViewById(R.id.imgButton);

        imgBtn.setOnClickListener(this);

                return view;
}


public void onClick(View v)
 {

            if(v.getId()==R.id.imgButton) 
        {
                     // TODO Auto-generated method stub

        startActivity(new Intent(ButtonFragment.this,Activity_One.class));
                Log.e(TAG,"Data show");     
                }
         }

Answer 1

你可以尝试：

startActivity(new Intent(v.getContext(),Activity_One.class));

并确保您已在Activity_One

中声明AndroidManifest.xml

按钮单击打开类扩展Fragment中的另一个活动
