Question

Hai Friends我是Android的新手..如何从ArrayAdapter类导航到另一个活动class.i不知道如何导航。我知道“intent”关键字用于将一个活动导航到另一个活动..但是现在我正在使用ArrayAdapter类，如果我使用“intent”关键字来导航另一个活动，我会收到错误。

package org.ajsquare.test;

import android.content.Context;
import android.content.Intent;
import android.content.res.TypedArray;
 import android.database.DataSetObserver;
 import android.graphics.Color;
 import android.sax.StartElementListener;
  import android.view.LayoutInflater;
  import android.view.View;
 import android.view.View.OnClickListener;
  import android.view.ViewGroup;
  import android.widget.ArrayAdapter;
  import android.widget.ImageView;
 import android.widget.ListAdapter;
 import android.widget.TextView;
 import android.widget.Toast;

 public class Teamname extends ArrayAdapter<String>
{



  private LayoutInflater mInflater;

private String[] mStrings;
private TypedArray mimages;
String mteam=null;
private int mViewResourceId;
Context c;

public Teamname(Context context, int textViewResourceId,TypedArray images,String[] test) {
    super(context, textViewResourceId,test);
    c=context;
    mimages=images;
    mViewResourceId=textViewResourceId;
    mInflater=(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    mStrings=test;
        }

public int getCount()
{

    return mStrings.length;
}

public String getId(int position)
{
    return mStrings[position];

}

public long getItemId(int position)
{

    return 0;

}


public View getView(final int position, View convertview, ViewGroup parent)
{

            convertview=mInflater.inflate(mViewResourceId, null);



    ImageView imageView=(ImageView)convertview.findViewById(R.id.image_teamname);
    imageView.setImageDrawable(mimages.getDrawable(position));
    imageView.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {


        System.out.println(position);

        //Intent intent=new Intent(Teamname.this,Team_details.class);// i am getting error from this line
                    //startActivity(this);

        }
    });

    return convertview;

}




     }

//我不能在这个类中使用意图..请给出解决方案

Answer 1

如果您的课程为NonActivityClass，请使用context开始新的活动....

Intent intent=new Intent(c,Team_details.class);
c.startActivity(intent);

Answer 2

Intent intent=new Intent(Teamname.this,Team_details.class); 
startActivity(this);

使用此代码并尝试::::

Intent intent=new Intent(Teamname.this,Team_details.class);
startActivity(intent);
