昨天我看见一个开发者发了一个问题,询问如何播放声音。目前由于一些原因在模拟器中没法测试。其实,播放声音很容易。如果使用qmake的话,可能需要做一些修改才可以正确地在手机上播放。
我们首先使用SDK来创建一个简单的项目(QML app with Simple UI "qmake")。我们记得修改我们的Main.qml如下:
import QtQuick 2.0 import Ubuntu.Components 1.1 import QtMultimedia 5.0 /*! \brief MainView with a Label and Button elements. */ MainView { // objectName for functional testing purposes (autopilot-qt5) objectName: "mainView" // Note! applicationName needs to match the "name" field of the click manifest applicationName: "audio.liu-xiao-guo" /* This property enables the application to change orientation when the device is rotated. The default is false. */ //automaticOrientation: true // Removes the old toolbar and enables new features of the new header. useDeprecatedToolbar: false width: units.gu(100) height: units.gu(75) Page { title: i18n.tr("Audio") SoundEffect { id: bubblepop source: "bubblepop.wav" volume: 1.0 } MediaPlayer { id: backgroundMusic source: "background.mp3" autoPlay: true loops: MediaPlayer.Infinite volume: 0.3 } Row { anchors.centerIn: parent Button { text: "Play bubble" onClicked: { bubblepop.play(); } } } } }
import QtMultimedia 5.0
添加“audio” security policy。由于我们使用qmake,所以在我们的应用中需要修改我们的.pro文件来包含我们的声音文件:
TEMPLATE = aux TARGET = audio RESOURCES += audio.qrc QML_FILES += $$files(*.qml,true) $$files(*.js,true) $$files(sounds/*.mp3,true) $$files(sounds/*.wav,true) CONF_FILES += audio.apparmor audio.desktop audio.png OTHER_FILES += $${CONF_FILES} $${QML_FILES} #specify where the qml/js files are installed to qml_files.path = /audio qml_files.files += $${QML_FILES} #specify where the config files are installed to config_files.path = /audio config_files.files += $${CONF_FILES} INSTALLS+=config_files qml_files
所有的源码在: git clone https://gitcafe.com/ubuntu/audio.git
