這篇文章主要介紹了Android開(kāi)發(fā)實(shí)現(xiàn)實(shí)時(shí)檢測(cè)藍(lán)牙連接狀態(tài)的方法,涉及Android針對(duì)藍(lán)牙連接狀態(tài)的監(jiān)測(cè)操作相關(guān)實(shí)現(xiàn)技巧,需要的朋友可以參考下

本文實(shí)例講述了Android開(kāi)發(fā)實(shí)現(xiàn)實(shí)時(shí)檢測(cè)藍(lán)牙連接狀態(tài)的方法。分享給大家供大家參考，具體如下：

本程序能實(shí)時(shí)監(jiān)聽(tīng)并檢測(cè)Android藍(lán)牙的連接狀態(tài)，無(wú)論是通過(guò)界面上的switch按鈕打開(kāi)/關(guān)閉手機(jī)藍(lán)牙，還是手動(dòng)打開(kāi)/關(guān)閉手機(jī)藍(lán)牙，程序都能監(jiān)聽(tīng)當(dāng)前的狀態(tài)。

一、軟件界面

二、程序?qū)崿F(xiàn)

① switch開(kāi)關(guān)—-打開(kāi)/關(guān)閉藍(lán)牙

Switch switchTest = (Switch) findViewById(R.id.switch1);
switchTest.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
 @Override
 public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
  if (isChecked) {
   mBluetoothAdapter.enable();//打開(kāi)藍(lán)牙
  } else {
   mBluetoothAdapter.disable();// 關(guān)閉藍(lán)牙
  }
 }
});

② 查看藍(lán)牙狀態(tài)監(jiān)聽(tīng)

Button btn = (Button) findViewById(R.id.button);
btn.setOnClickListener(new View.OnClickListener() {
 @Override
 public void onClick(View view) {
  Toast.makeText(MainActivity.this, "bluetooth is " +bluetoothStatus,
    Toast.LENGTH_SHORT).show();
 }
});

③ 監(jiān)聽(tīng)藍(lán)牙連接狀態(tài)

AndroidManifest權(quán)限設(shè)置：

<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>

監(jiān)聽(tīng)代碼：

//注冊(cè)藍(lán)牙監(jiān)聽(tīng)
mContext.registerReceiver(mReceiver, makeFilter());
//注銷(xiāo)藍(lán)牙監(jiān)聽(tīng)
//mContext.unregisterReceiver(mReceiver);
private IntentFilter makeFilter() {
  IntentFilter filter = new IntentFilter();
  filter.addAction(BluetoothAdapter.ACTION_STATE_CHANGED);
  return filter;
}
private BroadcastReceiver mReceiver = new BroadcastReceiver() {
  @Override
  public void onReceive(Context context, Intent intent) {
   switch (intent.getAction()) {
    case BluetoothAdapter.ACTION_STATE_CHANGED:
     int blueState = intent.getIntExtra(BluetoothAdapter.EXTRA_STATE, 0);
     switch (blueState) {
      case BluetoothAdapter.STATE_TURNING_ON:
       Log.e("TAG", "TURNING_ON");
       break;
      case BluetoothAdapter.STATE_ON:
       bluetoothStatus="on";
       Log.e("TAG", "STATE_ON");
       break;
      case BluetoothAdapter.STATE_TURNING_OFF:
       Log.e("TAG", "STATE_TURNING_OFF");
       break;
      case BluetoothAdapter.STATE_OFF:
       bluetoothStatus="off";
       Log.e("TAG", "STATE_OFF");
       break;
     }
     break;
   }
  }
};
