这是主要活动：
y<-rnorm(1000)
x<-rnorm(1000,1,2)
x1<-rnorm(1000,1,2)
par(mfrow=c(1,2))
plot(y,x,ylim=c(-4,4),xlim=c(-4,4))
plot(y,x1,ylim=c(-4,4),xlim=c(-4,4))
这是具有微调器和editText的Xml（如果我有编辑文本和弹出窗口，代码可以工作，但是当我添加微调器和更多文本框时，它没有显示所需的结果） 并且popup.xml只有CalendarView正在运行

使用以下方法显示弹出窗口并在EditText上设置所选日期。
private void showDatePicker() {
LayoutInflater inflater = (LayoutInflater)getApplicationContext().getSystemService
(Context.LAYOUT_INFLATER_SERVICE);
LinearLayout ll= (LinearLayout)inflater.inflate(R.layout.myLayout, null, false);
CalendarView cv = (CalendarView) ll.getChildAt(0);
cv.setOnDateChangeListener(new OnDateChangeListener() {
@Override
public void onSelectedDayChange(CalendarView view, int year, int month,
int dayOfMonth) {
edt.setText(year+"-"+month+"-"+dayOfMonth);
}
});
new AlertDialog.Builder(MomAppActivity.this)
.setTitle("Event Calendar")
.setMessage("Click to schedule or view events.")
.setView(ll)
.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
//do nothing...yet
}
}).setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
// Do nothing.
}
}
).show();
}

我曾经遇到同样的问题，但我更改了文本显示的自定义背景颜色。尝试更改背景或尝试设置不同的文本颜色。
