android不斷開關藍牙

文章的思路就是在主線程中設定一個按鈕，啟動一個線程，在子線程中進行線程的耗時操作，最後需要記住添加藍牙權限

AndroidManifest.xml中加入

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

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

public class MainActivity extends Activity {

Handler handle = new Handler() {
	 
    @Override

    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        startButton=(Button) findViewById(R.id.startButton);

    }

        @Override

             // 耗時操作           
        	int num=0;
        	while(true){
        		 BluetoothAdapter mBluetoothAdapter = BluetoothAdapter  
        	                .getDefaultAdapter();  
                  mBluetoothAdapter.disable();//關閉藍牙  
                  String string1=mBluetoothAdapter.getAddress();
                  
                  Log.e("test", "關閉"+mBluetoothAdapter.getState());
            try {

				e.printStackTrace();
			}
            mBluetoothAdapter.enable();
           
            String string=mBluetoothAdapter.getAddress();
            Message msg = new Message();
           
            num++;
            msg.arg1=num;
            Log.e("bluetest", "開啟"+mBluetoothAdapter.getState());
            Log.e("bluetest", string);
            Log.e("bluetest","總的次數"+num);
            handle.sendMessage(msg);
            try {

			} catch (InterruptedException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
            super.run();
        	}
        }
        
        
    }

}
           

這裡我在主界面更新開關的次數，也将開關的狀态的傳回值，打開的傳回值，藍牙的mac位址，和開關的次數輸出到了log之中。

這裡，謝謝我同僚b.z對我的提醒
