在 Android 12 中,通过使用设备间连接 (Device-to-Device Connection) 功能,可以实现蓝牙设备的自动配对和连接,而无需弹出配对提示框。这可以通过以下步骤来实现:
1. 在 AndroidManifest.xml 文件中添加 BLUETOOTH_CONNECT 和 BLUETOOTH_SCAN 权限:
```xml
<uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />
<uses-permission android:name="android.permission.BLUETOOTH_SCAN" />
```
2. 在您的应用程序中使用 BluetoothDevice.createBond() 方法进行设备配对:
```java
BluetoothDevice device = BluetoothAdapter.getDefaultAdapter().getRemoteDevice(address);
device.createBond();
```
3. 在您的应用程序中设置 BluetoothProfile.ServiceListener 接口来监听连接状态变化:
```java
private final BluetoothProfile.ServiceListener mProfileListener =
new BluetoothProfile.ServiceListener() {
@Override
public void onServiceConnected(int profile, BluetoothProfile proxy) {
if (profile == BluetoothProfile.A2DP) {
mA2dp = (BluetoothA2dp) proxy;
}
}
@Override
public void onServiceDisconnected(int profile) {
if (profile == BluetoothProfile.A2DP) {
mA2dp = null;
}
}
};
```
4. 在您的应用程序中使用 BluetoothDevice.connectGatt() 方法来连接设备:
```java
BluetoothDevice device = BluetoothAdapter.getDefaultAdapter().getRemoteDevice(address);
BluetoothGatt gatt = device.connectGatt(this, false, mGattCallback);
```
以上是在 Android 12 上实现蓝牙自动绑定的基本步骤,但具体实现需要结合您的应用程序和蓝牙设备的具体情况进行调整。同时,需要注意的是,在使用设备间连接功能时,需要保证您的应用程序已经获取了 BLUETOOTH_CONNECT 和 BLUETOOTH_SCAN 权限,否则将无法正常使用。
