由于项目需要，在关闭开关的时候需要将顶部的调温栏禁用，变为灰色且不可点击滑动，而开的时候要启用，变为黄色且可点击滑动

这里写图片描述

为防止抓不住重点，仅展示相关代码

public class DeviceControlActivity extends Activity implements View.OnClickListener,SeekBar.OnSeekBarChangeListener{    private SeekBar mSeekBar;    private TextView mLowTempTextView;    private TextView mMiddleTempTextView;    private TextView mHighTempTextView;    private Button mSwitchButton;    private int mSwitchButtonStatus =0;    @Override    protected void onCreate(@Nullable Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.device_control_layout);        initView();        intiData();        initEvent();    }    private void initView(){        mSeekBar=findViewById(R.id.id_seek_bar);    }    private void initEvent(){        mSeekBar.setOnSeekBarChangeListener(this);        setSeekBarClickable(0);//先禁用seekBar    }    @Override    public void onClick(View view) {        switch (view.getId()){            case R.id.id_device_control_switch_button:                if (mSwitchButtonStatus ==1){                    mSwitchButton.setBackgroundResource(R.drawable.switch_button_off_img);                    mSwitchButtonStatus =0;                    sendAt("AT+IO1=L");                    setSeekBarClickable(mSwitchButtonStatus);//禁用                }else {                    mSwitchButton.setBackgroundResource(R.drawable.switch_button_on_img);                    mSwitchButtonStatus =1;                    sendAt("AT+IO1=H");                    setSeekBarClickable(mSwitchButtonStatus);//启用                }                break;        }    }    private void setSeekBarClickable(int i){        if (i==1){            //启用状态            mSeekBar.setClickable(true);            mSeekBar.setEnabled(true);            mSeekBar.setSelected(true);            mSeekBar.setFocusable(true);            Drawable drawable=getResources().getDrawable(R.drawable.yellow_mid_img_40);            mSeekBar.setThumb(drawable);            mSeekBar.setProgress(50);        }else {            //禁用状态            mSeekBar.setClickable(false);            mSeekBar.setEnabled(false);            mSeekBar.setSelected(false);            mSeekBar.setFocusable(false);            Drawable drawable=getResources().getDrawable(R.drawable.seek_bar_grey_img_40);            mSeekBar.setThumb(drawable);            mSeekBar.setProgress(50);        }    }}
