如何在android中爲每個seekbar間隔設置文本？

Question

我正在搜索條中的Android，其最大值爲12

<SeekBar 
    android:id="@+id/seekBar1" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:layout_above="@+id/mapview" 
    android:layout_alignParentLeft="true" 
    android:layout_marginBottom="32dp" 
    android:max="12" 
    android:progress="0" 
    android:layout_marginTop="60dp" 
    android:secondaryProgress="0" /> 

我必須設置文本像1,2,3,4 .... 12我的XML設計下面對應的搜索條確切的時間間隔？如何實現這一目標？

Answer 1

請使用下面的代碼

<seek bar object>.setOnSeekBarChangeListener(new OnSeekBarChangeListener() 
      { 

       @Override 
       public void onProgressChanged(SeekBar arg0, int arg1, 
         boolean arg2) { 
        // TODO Auto-generated method stub 
        int mCurrentValue = arg1 + mMinValue; 
        text.setText(Integer.toString(mCurrentValue)); 
       } 

       @Override 
       public void onStartTrackingTouch(SeekBar arg0) { 
        // TODO Auto-generated method stub 

       } 

       @Override 
       public void onStopTrackingTouch(SeekBar arg0) { 
        // TODO Auto-generated method stub 

       } 

      });

首先，你得到你SeekBar參考：

SeekBar bar = (SeekBar) findViewById(R.id.seekBar1); 
bar.setOnSeekBarChangedListener(new OnSeek()); 

接下來創建一個實現OnSeekBarChangedListener的私有類：

private class OnSeek implements OnSeekBarChangeListener { 
    public void onProgressChanged(SeekBar seekBar, int progress, 
            boolean fromUser) { 
     //Here is where you handle the change in the seekbar e.g. 
     myTextView.setText("You are at stage: " + progress);  
    } 

    public void onStartTrackingTouch(SeekBar seekBar) { 
     //No need to do stuff here 
    } 

    public void onStopTrackingTouch(SeekBar seekBar) { 
     //No need to do stuff here 
    } 
    }
