次のように定義されたトグルボタンを持つクラスがあります。
public class DeviceControlActivity extends Activity implements View.OnClickListener
private ToggleButton b2, b3, b4, b5, b6, b7, b8, b9, b10, b11, b12;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.gatt_services_characteristics);
b2 = (ToggleButton) findViewById(R.id.button2);
b2.setOnClickListener(this); // calling onClick() method
b2.setBackgroundColor(Color.GRAY);
b3 = (ToggleButton) findViewById(R.id.button3);
b3.setOnClickListener(this);
b3.setBackgroundColor(Color.GRAY);
@Override
public void onClick(View v) {
// default method for handling onClick Events..
switch (v.getId()) {
case R.id.button2:
// call writeCharacteristic but concatenate pin #
if (b2.isChecked()) {
b2.setChecked(false);
b2.setBackgroundColor(Color.GRAY);
// do code to send pin# with writeCharacteristic
String str = "Pin11,0" + "\n";
Log.d(TAG, "Sending OFF result=" + str);
/*final byte[] tx = str.getBytes();
if(mConnected) {
characteristicTX2.setValue(tx);
mBluetoothLeService.writeCharacteristic(characteristicTX2);
mBluetoothLeService.setCharacteristicNotification(characteristicRX2,true);
}*/
} else if (!b2.isChecked()) {
b2.setChecked(true);
b2.setBackgroundColor(Color.BLUE);
// do code to send pin# with writeCharacteristic
String str = "Pin11,1" + "\n";
Log.d(TAG, "Sending ON result=" + str);
/*final byte[] tx = str.getBytes();
if(mConnected) {
characteristicTX2.setValue(tx);
mBluetoothLeService.writeCharacteristic(characteristicTX2);
mBluetoothLeService.setCharacteristicNotification(characteristicRX2, true);
}*/
}
break;
}
}
アプリを実行してb2をトグルすると、xmlでトグルボタンがfalseとして宣言され、ボタンがオンまたはオフに切り替わらない場合でも、ifのSending OFF結果部分が常に取得されます。
なぜこうなった?
