我有一个包含一个搜索栏和一个TextView自定义警告对话框。我想，当用户使用搜索栏。

I have a custom alert dialog which contains a seekbar and a textview. I want to display progress of seekbar in that textview in percents when the user interacts with the thumb of seekbar..

这是我的code ..

here is my code..

AlertDialog.Builder builder = new AlertDialog.Builder(PrefsActivity.this);
LayoutInflater inflater = getLayoutInflater();
View layoutFromInflater = inflater.inflate(R.layout.dialog_fragment_sensitivity_layout, null);      
builder.setView(layoutFromInflater)
    .setPositiveButton("Ok", new OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {

        }
    }).setNegativeButton("Cancel", new OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            dialog.cancel();
        }
    });


    final AlertDialog dialog = builder.create();
    dialog.show();

    TextView progress_tv = (TextView) dialog.findViewById(R.id.seekbar_progress_tv2);           
    progress_tv.setText("sdf"); 
    SeekBar seekBar = (SeekBar) dialog.findViewById(R.id.seekBar1); 
    seekBar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {

        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {
        }

        @Override
        public void onStartTrackingTouch(SeekBar seekBar) { 
        }

        @Override
        public void onProgressChanged(SeekBar seekBar, int progress,boolean fromUser) {                             
            System.out.println("progress... " + progress);      
            progress_tv.setText(progress);  // Exception...
        }
    });

里面onSeekBarChangeListener ResourceNotFound例外，我设置搜索栏的进展到TextView的。

ResourceNotFound exception inside onSeekBarChangeListener where i set the progress of seekbar to that textview.

TextView progress_tv = (TextView) dialog
                .findViewById(R.id.seekbar_progress_tv2);

和

TextView progress_tv = (TextView) layoutFromInflater
                    .findViewById(R.id.seekbar_progress_tv2);

但仍然问题仍然存在。

but still problem persist..

任何帮助是AP preciated ..

Any help is appreciated..

推荐答案

的TextView 期望得到的CharSequence ，你传递一个int给它。解决方法之一是 Integer.toString（进度）

TextView expects to get charSequence and you pass an int to it. One way to solve this is Integer.toString(progress)
