SeekBar的基础试用

参考：http://blog.csdn.net/qq_28057577/article/details/52225870

<SeekBar

                android:id="@+id/change_surge_seekbar"

                android:layout_width="match_parent"

                android:layout_height="wrap_content"

                android:max="100"

                android:progress="50" />

max:最大进度
progress:当前进度

surgeSeekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {

            @Override

            public void onProgressChanged(SeekBar seekBar, int i, boolean b) {



            }



            @Override

            public void onStartTrackingTouch(SeekBar seekBar) {

                Toast.makeText(ChangeActivity.this,"slide to change surge",Toast.LENGTH_SHORT).show();

            }



            @Override

            public void onStopTrackingTouch(SeekBar seekBar) {

                Toast.makeText(ChangeActivity.this, "surge is"+surgeSeekBar.getProgress()*2+"%", Toast.LENGTH_SHORT).show();

            }

        });

onProgressChanges:进度改变时
onStartTrackingTouch:按住SeekBar时
onStopTrackingTouch:放开SeekBar时
