获取android seekbar值并将其显示在屏幕上

问题描述

我试图获取搜索栏的值，只要它发生变化并在下面显示它.我正在我的搜索栏中使用onclick方法来调用此方法.

I'm trying to get the value of the seek bar whenever it changes and display it underneath. I'm using the onclick method on my seekbar to call this method.

public void getNumber(View view)
{
    SeekBar seek = (SeekBar) findViewById(R.id.seekBar1);
    int seekValue = seek.getProgress();
    String x = "Value: " + Integer.toString(seekValue);
    ((TextView) findViewById(R.id.level)).setText(x);
}

推荐答案

这里有一些额外的帮助:

Here some extra help:

import android.app.Activity;
import android.os.Bundle;
import android.widget.SeekBar;
import android.widget.TextView;

public class AndroidSeekBar extends Activity {
   /** Called when the activity is first created. */
   @Override
   public void onCreate(Bundle savedInstanceState)
       super.onCreate(savedInstanceState);
       setContentView(R.layout.main);

       SeekBar seekBar = (SeekBar)findViewById(R.id.seekbar);
       final TextView seekBarValue = (TextView)findViewById(R.id.seekbarvalue);

       seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener(){

   @Override
   public void onProgressChanged(SeekBar seekBar, int progress,
     boolean fromUser) {
    // TODO Auto-generated method stub
    seekBarValue.setText(String.valueOf(progress));
   }

   @Override
   public void onStartTrackingTouch(SeekBar seekBar) {
    // TODO Auto-generated method stub
   }

   @Override
   public void onStopTrackingTouch(SeekBar seekBar) {
    // TODO Auto-generated method stub
   }
       });
   }
}

使用OnProgressChanged事件检查搜索栏的进度，您可以将该int返回以在应用程序中的其他地方使用它.

use the OnProgressChanged event to check the progress of the seekbar, you can return that int to use it somewhere else in your app.
