Implementations§

source§

impl AudioManager

source

pub const ACTION_HEADSET_PLUG: &'static str = "android.intent.action.HEADSET_PLUG"

广播操作:有线耳机已插入或拔出。您无法通过清单中声明的​​组件接收此信息,只能通过使用 Context.registerReceiver() 明确注册来接收。 意图将具有以下额外值: state - 0 表示拔出,1 表示插入。 name - 耳机类型,人类可读的字符串 microphone - 如果耳机有麦克风则为 1,否则为 0

Methods from Deref<Target = GlobalRef>§

source

pub fn as_obj(&self) -> &JObject<'static>

Get the object from the global ref

This borrows the ref and prevents it from being dropped as long as the JObject sticks around.

Methods from Deref<Target = JObject<'static>>§

source

pub fn as_raw(&self) -> *mut _jobject

Returns the raw JNI pointer.
