本文实例为大家分享了Android SeekBar实现禁止滑动的具体代码，供大家参考，具体内容如下

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

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);
 }
 }
}
