Android是一个用于调整位图亮度的搜索栏

Question

我尝试过很多代码,看过Android开发人员,但无法使其工作.我希望搜索栏调整我的位图图像亮度

Answer 1

检查增加/减少图像亮度时给出的示例

并按照下面的搜索栏进度更改执行操作

 int brightness;
 SeekBar seekbarbrightness=(SeekBar)findViewById(R.id.seekBar1);
 seekbarbrightness.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {

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

         }

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

         }

         @Override
         public void onProgressChanged(SeekBar arg0, int progress, boolean arg2) {

             // TODO Auto-generated method stub

             brightness=progress;
             Bitmap bitmap=doBrightness(originalbitmap,brightness);
             imageView.setImageBitmap(bitmap);
         }
        });
