Android 如何通过单击按钮在listview中获取所选项目

Android 如何通过单击按钮在listview中获取所选项目,android,listview,button,Android,Listview,Button,我有一个带有textView的listview,每行中都有一个按钮,我试图通过单击按钮来获取文本,而不是单击整行,但是adapterView方法:(adapterView arg0,View v,int position,long arg3)不适用于按钮单击 public View getView(int position, View convertView, ViewGroup parent) { //Set the view for each item in the list

我有一个带有textView的listview,每行中都有一个按钮,我试图通过单击按钮来获取文本,而不是单击整行,但是adapterView方法:(adapterView arg0,View v,int position,long arg3)不适用于按钮单击

public View getView(int position, View convertView, ViewGroup parent) {
        //Set the view for each item in the list view
        View v = convertView;
        if (v == null) {
            LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            v = vi.inflate(R.layout.employeeitem, null);
        }
        //Get the Textviews from the row view and set the appropriate values for them
        TextView labelName=(TextView) v.findViewById(R.id.labelName);
        TextView labelAddress=(TextView)v.findViewById(R.id.labelAddress);
        TextView labelImmat=(TextView)v.findViewById(R.id.labelImmat);
        labelName.setText(array[position].marque);
        labelAddress.setText(array[position].categorie);
       labelImmat.setText(array[position].Prix_Achats);
        return v;
    }
这是我通过单击listview的行来选择项目的方式,但我希望通过单击按钮而不是整行来选择项目:

listEmployeeDetails.setOnItemClickListener(new OnItemClickListener(){

           public void onItemClick(AdapterView<?> arg0, View v,int position, long arg3)
     {

             TextView tv=(TextView)v.findViewById(R.id.labelName);
             String name=tv.getText().toString();


             Toast.makeText(getApplicationContext(), "Contact Selected "+name, Toast.LENGTH_LONG).show();
     }
    });
listEmployeeDetails.setOnItemClickListener(新的OnItemClickListener(){
public void onItemClick(AdapterView arg0,视图v,内部位置,长arg3)
{
TextView tv=(TextView)v.findViewById(R.id.labelName);
字符串名称=tv.getText().toString();
Toast.makeText(getApplicationContext(),“选定联系人”+姓名,Toast.LENGTH\u LONG.show();
}
});

为您的按钮设置onClickListener:

Button button = (Button) getActivity().findViewById(R.id.button);

button.setOnClickListener(new View.OnClickListener() {

    public void onClick(View v) {
       // button was clicked
    }

});

我使用游标适配器做了类似的事情

在适配器内部定义onClickListener。在此之前,您必须使用
getTag
setTag
函数在函数中发送和检索要恢复的信息

myButton.setTag("Value I want to store");

    myButton.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            String value = (String) v.getTag();
            //Whatever you want to do
        }
    });

希望有帮助:)

您可以在按钮上设置一个标记,从
getView()
方法访问它。当以编程方式或通过xml声明项时,可以在标记中存储该项的文本

public View getView(int position, View convertView, ViewGroup parent) {
    //Set the view for each item in the list view
    View v = convertView;
    //Do your view stuff here
    Button btn = (Button)v.findViewById(R.id.your_button_id);
    btn.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            String str = (String)v.getTag();
            //Do whatever you want with your str here
        }
    });
    return v;
}
listView2.setOnItemClickListener(新的AdapterView.OnItemClickListener(){
@凌驾
public void onItemClick(AdapterView父级、视图、,
内部位置,长id){
Toast.makeText(getApplicationContext(),“单击”+parent.getItemAtPosition(position).toString(),Toast.LENGTH\u SHORT).show();
}
});
parent.getItemAtPosition(position.toString()


此方法返回该位置的当前选定项

通过单击按钮从textview获取文本

    btn.setTag(textView.getText().toString());
btn.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub


        String s =(String)v.getTag();


    }
});

我花了三天时间才解决这个问题,但解决办法是显而易见的。我的列表是使用
JSONArray
SQL
服务器扩展而来的,在
getView()
方法中,我要做的就是在使用jsonOjbect扩展后,将
TextView
传递到按钮的
setTag()
。然后在按钮的
onClick()
方法中,我必须获得标签。看一下代码,希望对我有所帮助

@Override
public View getView(int position, View convertView, ViewGroup parent) {

   ListCell cell;//ListCell is my widgets class holder

    //set up the convertView

    if(convertView==null){

        convertView=inflater.inflate(R.layout.menu_custom_layout, null);
        cell=new ListCell();
        cell.Diet=(TextView)convertView.findViewById(R.id.dietEat); //Diet is the custom list layout textview
        cell.eatButton=(Button)convertView.findViewById(R.id.eatButtton); //eatButton is the button to be clicked
        cell.eatButton.setOnClickListener(this);

    }else{
        cell=(ListCell)convertView.getTag();

    }

    //Change data of each cell
    try {

        JSONObject jsonObject=this.dataArray.getJSONObject(position);
        cell.Diet.setText(jsonObject.getString("food_name"));
        cell.eatButton.setTag(cell.Diet.getText()); //Tag for button's onclick Listener

    } catch (JSONException e) {

        e.printStackTrace();

    }

    return convertView;
}

                @Override
public void onClick(View v) {

String fud=(String) v.getTag(); //Getting the tag and parsing it to string

}

发布适配器getView代码。这不是我的问题,我的问题是如何通过单击按钮获取listview行中的文本
@Override
public View getView(int position, View convertView, ViewGroup parent) {

   ListCell cell;//ListCell is my widgets class holder

    //set up the convertView

    if(convertView==null){

        convertView=inflater.inflate(R.layout.menu_custom_layout, null);
        cell=new ListCell();
        cell.Diet=(TextView)convertView.findViewById(R.id.dietEat); //Diet is the custom list layout textview
        cell.eatButton=(Button)convertView.findViewById(R.id.eatButtton); //eatButton is the button to be clicked
        cell.eatButton.setOnClickListener(this);

    }else{
        cell=(ListCell)convertView.getTag();

    }

    //Change data of each cell
    try {

        JSONObject jsonObject=this.dataArray.getJSONObject(position);
        cell.Diet.setText(jsonObject.getString("food_name"));
        cell.eatButton.setTag(cell.Diet.getText()); //Tag for button's onclick Listener

    } catch (JSONException e) {

        e.printStackTrace();

    }

    return convertView;
}

                @Override
public void onClick(View v) {

String fud=(String) v.getTag(); //Getting the tag and parsing it to string

}
