Android Dialog对话框的使用特别广泛,特别是AlertDialog和ProgressDialog这两个类用得最多,下面分别对Android的各种类型对话框的使用进行总结,此篇文章并非小编远程,文章来源于CSDN网站,小编只是作为笔记记录在自己的网站中。
1、确定取消对话框
// 使用AlertDialog.Builder初始化对话框 AlertDialog.Builder builder0 = new AlertDialog.Builder(context); // 设置图标 builder0.setIcon(R.mipmap.ic_launcher); // 设置标题 builder0.setTitle("确定取消对话框"); // 设置显示内容 builder0.setMessage("点击确定还是取消?"); // 确定按钮 builder0.setPositiveButton("确定", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { Toast.makeText(context, "您点击了确定!", Toast.LENGTH_SHORT).show(); } }); // 中立按钮(常用作忽略) builder0.setNeutralButton("忽略", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { Toast.makeText(context, "您选择了忽略!", Toast.LENGTH_SHORT).show(); } }); // 取消按钮 builder0.setNegativeButton("取消", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { Toast.makeText(context, "您点击了取消!", Toast.LENGTH_SHORT).show(); } }); // 创建对话框并展示 builder0.create().show();
效果如图所示:
2、列表对话框
final String[] items = {"苹果", "桃子", "梨", "李子", "香蕉", "橘子"}; AlertDialog.Builder builder1 = new AlertDialog.Builder(context); builder1.setIcon(R.mipmap.ic_launcher); builder1.setTitle("选择你喜欢的水果"); // 注意:如果是列表形式的对话框,就不能有message // 设置列表并绑定点击事件 builder1.setItems(items, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { Toast.makeText(context, "你最喜欢的水果是" + items[which] + "!", Toast.LENGTH_SHORT).show(); } }); builder1.create().show();
效果如图所示:
3、条形进度条对话框
private boolean isThreadInterrupted; // 标识进度条是否被隐藏,即线程是否被销毁 // 通过new的方式直接创建ProgressDialog final ProgressDialog progressDialog2 = new ProgressDialog(context); progressDialog2.setIcon(R.mipmap.ic_launcher); progressDialog2.setTitle("正在下载文件......"); // 设置进度条的样式(这里是横向的进度条) progressDialog2.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); // 设置最大进度 progressDialog2.setMax(100); // 当进度对话框正在加载数据的时候,如果点击对话框外围,不隐藏对话框 progressDialog2.setCanceledOnTouchOutside(false); // 新建线程加载进度 final Thread loadThread = new Thread(new Runnable() { @Override public void run() { int progress = 0; while (++progress <= 100) { if (!isThreadInterrupted) { progressDialog2.incrementProgressBy(1); try { Thread.sleep(100); } catch (InterruptedException e) { e.printStackTrace(); } } } if (!isThreadInterrupted) { // 进度加载完成后隐藏对话框,同时弹出Toast context.runOnUiThread(new Runnable() { @Override public void run() { progressDialog2.dismiss(); Toast.makeText(context, "文件下载完成!", Toast.LENGTH_SHORT).show(); } }); } else { // 重置,下次点击ListView的这个Item时可以重新开启线程下载 isThreadInterrupted = false; } } }); loadThread.start(); // 设置一个按钮,第一个参数是指定这个按钮的作用(Positive/Negative/Neutual) progressDialog2.setButton(ProgressDialog.BUTTON_NEGATIVE, "取消下载", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { dialog.dismiss(); // 点击取消下载按钮后阻塞下载线程 isThreadInterrupted = true; } }); // 显示对话框 progressDialog2.show();
效果如图所示:
4、圆形进度条对话框
// 如果不指定Dialog类的ProgressStyle,则默认显示一个圆形的进度框 final ProgressDialog progressDialog6 = new ProgressDialog(context); progressDialog6.setMessage("正在加载......"); progressDialog6.setCanceledOnTouchOutside(false); progressDialog6.show(); // 进度条三秒后消失,同时弹出Toast new Handler().postDelayed(new Runnable() { @Override public void run() { context.runOnUiThread(new Runnable() { @Override public void run() { progressDialog6.dismiss(); Toast.makeText(context, "加载完成!", Toast.LENGTH_SHORT).show(); } }); } }, 3000);
效果如图所示:
5、多选列表对话框
final String[] items = {"苹果", "桃子", "梨", "李子", "香蕉", "橘子"}; final boolean[] checkState = {false, false, false, false, false, false}; final AlertDialog.Builder builder4 = new AlertDialog.Builder(context); builder4.setIcon(R.mipmap.ic_launcher); builder4.setTitle("选择你喜欢的水果"); // 设置多选选项,并绑定点击事件 builder4.setMultiChoiceItems(items, new boolean[]{false, false, false, false, false, false}, new DialogInterface.OnMultiChoiceClickListener() { @Override public void onClick(DialogInterface dialog, int which, boolean isChecked) { checkState[which] = isChecked; } }); // 点击“确定”按钮后输出选中的选项 builder4.setPositiveButton("确定", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { String message = ""; boolean first = true; for (int i = 0; i < items.length; i++) { if (checkState[i]) { if (first) { message += items[i]; first = false; } else { message += "、" + items[i]; } } } if ("".equals(message)) { message = "看来您不喜欢吃水果"; } Toast.makeText(context, "您喜欢的水果有:" + message, Toast.LENGTH_SHORT).show(); } }); builder4.setNegativeButton("取消", null); builder4.create().show();
效果如图所示:
6、单选列表对话框
final String[] items = {"苹果", "桃子", "梨", "李子", "香蕉", "橘子"}; final AlertDialog.Builder builder3 = new AlertDialog.Builder(context); builder3.setIcon(R.mipmap.ic_launcher); builder3.setTitle("选择你喜欢的水果"); // 设置单选选项,默认选中第一个,并绑定点击事件 builder3.setSingleChoiceItems(items, 0, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { Toast.makeText(context, "你最喜欢的水果是" + items[which] + "!", Toast.LENGTH_SHORT).show(); // 选中某一项后关闭对话框 dialog.dismiss(); } }); builder3.create().show();
效果如图所示:
7、日期选择对话框
// 获取当前的年月日 Calendar calendar = Calendar.getInstance(); int year = calendar.get(Calendar.YEAR); int month = calendar.get(Calendar.MONTH); int dayOfMonth = calendar.get(Calendar.DAY_OF_MONTH); // 创建DatePickerDialog DatePickerDialog datePickerDialog = new DatePickerDialog(context, new DatePickerDialog.OnDateSetListener() { @Override public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) { // 得到的月份会比实际月份少1 Toast.makeText(context, year + "-" + (month + 1) + "-" + dayOfMonth, Toast.LENGTH_SHORT).show(); } }, year, month, dayOfMonth); // 显示对话框 datePickerDialog.show();
效果如图所示:
8、事件选择对话框
// 获取当前时间(时、分) Calendar calendar = Calendar.getInstance(); int hourOfDay = calendar.get(Calendar.HOUR_OF_DAY); int minute = calendar.get(Calendar.MINUTE); // 初始化TimePickerDialoy,最后一个参数决定是否是24小时制 TimePickerDialog timePickerDialog = new TimePickerDialog(context, new TimePickerDialog.OnTimeSetListener() { @Override public void onTimeSet(TimePicker view, int hourOfDay, int minute) { Toast.makeText(context, hourOfDay + ":" + minute, Toast.LENGTH_SHORT).show(); } }, hourOfDay, minute, true); // 显示对话框 timePickerDialog.show();
效果如图所示:
9、Android自定义对话框
自定义对话框代码如下:
final AlertDialog.Builder builder5 = new AlertDialog.Builder(context); builder5.setIcon(R.mipmap.ic_launcher); builder5.setTitle("自定义对话框"); // 使用LayoutInflater创建一个自定义布局 View customView = LayoutInflater.from(context).inflate(R.layout.dialog_custom, null); final TextView tvName = (TextView) customView.findViewById(R.id.id_customdialog_username); final TextView tvPassword = (TextView) customView.findViewById(R.id.id_customdialog_password); // 为对话框设置自定义布局 builder5.setView(customView); builder5.setPositiveButton("确定", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { String username = tvName.getEditableText().toString().trim(); String password = tvPassword.getEditableText().toString().trim(); Toast.makeText(context, "您的用户名是" + username + ",密码是" + password, Toast.LENGTH_SHORT).show(); } }); builder5.setNegativeButton("取消", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { dialog.dismiss(); } }); builder5.create().show();
自定义对话框dialog_custom.xml布局文件代码:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="vertical" android:paddingBottom="15.0dip" android:paddingLeft="20.0dip" android:paddingRight="20.0dip" android:paddingTop="10.0dip"> <EditText android:id="@+id/id_customdialog_username" android:layout_width="match_parent" android:layout_height="wrap_content" android:hint="Input your name" android:inputType="text" /> <EditText android:id="@+id/id_customdialog_password" android:layout_width="match_parent" android:layout_height="wrap_content" android:hint="Input your password" android:inputType="textPassword" /> </LinearLayout>
效果如图所示:
