Android通过拖动搜索栏右和左控制视图高度

Question

我的问题是我有一个View和seekbar.now我想在SeekBar的帮助下控制视图的高度。当SeekBar向右拖动时视图高度增加，向左拖动时视图高度减小。 ..我想要它，我已经在示例图片中解释..

当我向右拖动搜索栏时，视图高度会增加。当我向左拖动搜索栏时，视图高度会降低。任何帮助都会非常感激。谢谢Alot提前。

我已根据您的要求实现了demo.Adjust高度。希望您能有所了解。

这是一个很好的代码，但希望你能从中得到它的想法

  

SeekBar seekBar =（SeekBar）layout.findViewById（R.id.seekbar）;   seekBar.setProgress（1）; seekBar.incrementProgressBy（10）;   seekBar.setMax（100）;

     

seekBar.setOnSeekBarChangeListener（新   SeekBar.OnSeekBarChangeListener（）{

@Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
   if(progress == 0)          {
          progress = 10;          }
                  int height = progress/10; //let suppose 10 is your maximum height of your view to resize
      linearlayoutToResize.setLayoutParams(new

     

FrameLayout.LayoutParams（30，height））;       }

@Override
public void onStartTrackingTouch(SeekBar seekBar) {

}

@Override
public void onStopTrackingTouch(SeekBar seekBar) {            

} });
