Record holder自定义适配器的问题

标签： android

我有listview的listAdapter，我在自定义适配器中设置了记录按钮。我已将代码置于holder.record的点击事件中

holder.record.setBackgroundResource(R.drawable.record_green);

用户触摸时设置该按钮的背景。但我的问题是，当我触摸特定列表项按钮时，此图像将应用于另一个列表项

以下是代码： 

holder.record.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {

        if (isplaying2 == true) {

        } else
        { 
            if (b_Flag_Record_or_not == true) {
            } else {
                try {

                    holder.record.setBackgroundResource(R.drawable.record_green);
                    b_Flag_Record_or_not = true;
                    b_play_or_not = true;

                    flag_stop_position = position;
                    AuthHandler dataHandler = new AuthHandler();
                    AuthDataset dataset = dataHandler
                            .getParsednewJobdtl_DataSet();

                    System.out.println("dataset.getint1();"
                            + dataset.getint1());
                    // Login l = new Login();
                    String str_useid = RequestTo[position];
                    recorder = new AudioRecorder("/audiometer/shanesh"
                            + RequestId[position] + "-" + str_useid);
                    start_or_not = true;
                    recorder.start();
                    Toast.makeText(context, "Start Recording", Toast.LENGTH_LONG).show();
                    CountDownTimer countDowntimer = new CountDownTimer(
                            120000000, 1000) {
                        public void onTick(long millisUntilFinished) {
                        }

                        public void onFinish() {
                            try {
                                Toast.makeText(
                                        context,
                                        "Stop recording Automatically ",
                                        Toast.LENGTH_LONG).show();
                                recorder.stop();
                            } catch (Exception e) {
                                // TODO Auto-generated catch block
                                e.printStackTrace();
                            }
                        }
                    };
                    countDowntimer.start();

                } catch (IOException e) {
                    Writer writer = new StringWriter();
                    PrintWriter printWriter = new PrintWriter(writer);
                    e.printStackTrace(printWriter);
                    String s = writer.toString();

                }catch (Exception e) {

                }
            }

        }
    }
});

请参阅Holder用于在适配器视图中重复使用视图，因此如果屏幕可以显示5个项目一次，则第6个项目将重复使用项目1的视图，因此持有者。

使用ListView.onItemClickListener而不是holder.record.setOnClickListener（），或者将视图背景设置为getView方法，我在getVIew方法中编辑你的代码：

    public class ListViewAdapter extends BaseAdapter {

public static Activity context;

String title[];
String description[];
String RequestId[];
String Folderpath[];
String RequestTo[];

boolean b_Flag_Record_or_not = false;
boolean b_upload_or_not = false;
boolean start_or_not = false;
boolean start_play = false;
boolean upload_or_not = false;
boolean b_play_or_not = false;
boolean isplaying2 = false;
