我按照此guide继承了一个类,但是因dalvik.system.NativeStart.main(native method)
错误而崩溃
var MyDatePicker = android.widget.DatePicker.extend({
init: function() {
var isConstructor = arguments[arguments.length - 1];
if (isConstructor) {
// we are called from Java constructor
console.log('con')
} else {
// we are called from Java init method
console.log('init');
}
}
});
var foo = new MyDatePicker();
答案 0 :(得分:1)
根据Android文档(http://developer.android.com/reference/android/widget/DatePicker.html),DatePicker构造函数至少需要一个参数(上下文)。尝试传递它,例如
var foo = new MyDatePicker(context);
