利用runBackground 模块来解决双击返回键退出的代码
//安卓应用
var isAndroid = (/android/gi).test(navigator.appVersion);
if(isAndroid){
var rb = api.require('runBackground');
rb.hideActivity();
}
//绑定安卓的后退按钮事件 两秒内后退按钮点击两次 退到后台运行
var backSecond = 0;
api.addEventListener({
name : 'keyback'
}, function (ret, err) {
var curSecond = new Date().getSeconds();
if (Math.abs(curSecond - backSecond) > 2) {
backSecond = curSecond;
api.toast({
msg : '连续按两次到后台运行',
duration : 2000,
location : 'bottom'
});
} else {
var rb = api.require('runBackground');
rb.hideActivity();
}
}); |
