                final ComponentName cn = new ComponentName("com.android.settings", "com.android.settings.bluetoothSettings");
                intent.setComponent(cn);

            }
        });

推荐答案

使用

use

而不是

final ComponentName cn = new ComponentName("com.android.settings", 
                              "com.android.settings.bluetoothSettings");

要推出BluetoothSettings设置

to launch BluetoothSettings settings
