Java 显示对话框未显示
在Java 显示对话框未显示,java,android,date,dialog,Java,Android,Date,Dialog,在活动中，我调用了不同的片段，我希望用户能够通过单击显示当前日期的文本视图来更改日期，显示对话框不希望显示 dateView.setOnClickListener(new View.OnClickListener() { @SuppressWarnings("deprecation") public void onClick(View v) { getActivity().showDialog(999); } }); Android Studio告诉我，
活动文本视图显示对话框dateView.setOnClickListener(new View.OnClickListener() {
@SuppressWarnings("deprecation")
public void onClick(View v) {
getActivity().showDialog(999);
}
});
