我使用setEnabled(false)来设置它无法,但它不起作用.在此方法之后,RadioGroup.IsEnabled()的值为false.价值改变了.

该代码来自Android编程指南.Ps:Spinner组件使用setEnabled(false)很好.

代码如下:

package com.example.testviews;

import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.RadioGroup;

public class TestRadioGroup extends Activity {


@Override
public void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.radiogroup);

    final RadioGroup testRadioGroup = (RadioGroup) findViewById(R.id.testRadioGroup);

    final Button changeEnabledButton = (Button) findViewById(R.id.changeEnabledButton);
    changeEnabledButton.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {
            // TODO Auto-generated method stub
            changeEnabled(testRadioGroup);
        }
    });

    final Button changeBgColorButton = (Button) findViewById(R.id.changeBackgroundColorButton);
    changeBgColorButton.setOnClickListener(new OnClickListener() {

        public void onClick(View v) { …

我最近收到了Crash Report Tools的崩溃报告.这次崩溃是指UIWebView WebCore崩溃,我的应用程序仅使用UIWebView,而我最近无法切换到WKWebview.下面是崩溃报告,我无法重现它.它发生在设备iPhone 6,7,8,X上,但只使用iOS 11.3版本(15E216).

这次崩溃有3个不同的崩溃堆栈.任何意见将是有益的.

我正在编写一个日历视图.当我按下一个月的按钮时,我调用了mCalendarContainerLL.invalidate();但我的自定义视图没有被重绘.我的自定义视图中的onDraw方法没有被调用.

Ps:如果我直接使所有日历单元格视图无效.它有效.为什么会这样？

这是代码:

private CalendarWidgetDayCell updateCalendarView() {

        CalendarWidgetDayCell dayCellSelected = null;
        boolean isSelected = false;

        final boolean isHasSelection = (mCalendarSelected.getTimeInMillis() != 0);

        final int selectedYear = mCalendarSelected.get(Calendar.YEAR);
        final int selectedMonth = mCalendarSelected.get(Calendar.MONTH);
        final int selectedDay = mCalendarSelected.get(Calendar.DAY_OF_MONTH);

        Calendar dateXOfCalendar = Calendar.getInstance();
        dateXOfCalendar.setTimeInMillis(mStartDateCurrentMonth.getTimeInMillis());

        Log.d(tag, "updateCalendarView cpt_func_ " + "mDayCellList.size(): " + mDayCellList.size());
        for (int i = 0; i < mDayCellList.size(); i++) {
            final int yearOfCellItem = dateXOfCalendar.get(Calendar.YEAR);
            final int monthOfCellItem = dateXOfCalendar.get(Calendar.MONTH);
            final int dayOfCellItem = dateXOfCalendar.get(Calendar.DAY_OF_MONTH);
            final int dayOfWeekOfCellItem = …
