getFreq

public int getFreq()

Obtains the frequency of the radio signal.

返回:

Returns the radio signal frequency.

从以下版本开始:

3

getStereo

public int getStereo()

Obtains the radio stereo volume.

返回:

Returns the radio stereo volume.

从以下版本开始:

3

getSignalSatisfied

public boolean getSignalSatisfied()

Checks whether the radio signal strength reaches the threshold.

返回:

Returns true if the threshold is reached; returns false otherwise.

从以下版本开始:

3

setSignalQuality

public void setSignalQuality(int signalQuality)

Sets the radio signal strength.

参数:

signalQuality - Indicates the signal strength to set. A larger value indicates stronger signal strength.

从以下版本开始:

3

setFreq

public void setFreq(int freq)

Sets the frequency of the radio signal.

参数:

freq - Indicates the radio signal frequency.

从以下版本开始:

3

setStereo

public void setStereo(int stereo)

Sets radio stereo volume.

参数:

stereo - Indicates the stereo volume.

从以下版本开始:

3

setSignalSatisfied

public void setSignalSatisfied(boolean signalSatisfied)

Sets whether the radio signal strength reaches the threshold.

参数:

signalSatisfied - Specifies whether the signal strength reaches the threshold. Value true means that the threshold is reached, and false means the opposite.

marshalling

public boolean marshalling(ohos.utils.Parcel out)

Marshals a ProgramInfo object into a Parcel.

指定者:

marshalling 在接口中 ohos.utils.Sequenceable

参数:

out - Indicates the Parcel object into which the ProgramInfo object will be written.

返回:

Returns true if marshalling is successful; returns false otherwise.

unmarshalling

public boolean unmarshalling(ohos.utils.Parcel in)

Unmarshals a ProgramInfo object from a Parcel.

指定者:

unmarshalling 在接口中 ohos.utils.Sequenceable

参数:

in - Indicates the Parcel object into which the ProgramInfo object has been written.

返回:

Returns true if unmarshalling is successful; returns false otherwise.
