如何通过单击按钮在列表视图中获取选定的项目

Question

我有一个带有textView的列表视图，每行都有一个按钮，我试图通过单击按钮而不是通过单击整行来获取文本view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;
    }

这就是我如何通过单击列表视图的行来选择项目，但是，我想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();
     }
    });

Answer 1

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();


    }
});

Answer 2

您可以为按钮设置一个标签以从getView（）方法访问它。当您以编程方式或通过xml声明项目时，您可以在标签中存储该项目的文本。

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;
}

Answer 3

将 onClickListener 设置为您的按钮：

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

button.setOnClickListener(new View.OnClickListener() {

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

});
