SeekBar事件，被拉动时，onProgressChanged会一直被触发

1 public void showSeekBar() { 2         seekBar = (SeekBar) findViewById(R.id.seekBar1); 3         seekBar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() { 4  5             @Override 6             public void onStopTrackingTouch(SeekBar seekBar) { 7                 // TODO Auto-generated method stub 8                 Log.i(TAG, "onStopTrackingTouch"); 9                 Toast.makeText(FormActivity.this,10                         "current level is " + seekBar.getProgress(), 3000)11                         .show();12             }13 14             @Override15             public void onStartTrackingTouch(SeekBar seekBar) {16                 // TODO Auto-generated method stub17                 Log.i(TAG, "onStartTrackingTouch");18 19             }20 21             @Override22             public void onProgressChanged(SeekBar seekBar, int progress,23                     boolean fromUser) {24                 // TODO Auto-generated method stub25                 Log.i(TAG, "onProgressChanged");26 27             }28         });29     }
