如何将复选框添加到警报对话框 [英] How to add a check box to an alert dialog

问题描述

目前，当用户打开我的应用时，会打开一个 AlertDialog，询问他们是否要升级到专业版.

Currently when the user opens my app, an AlertDialog opens, asking them if they would like to upgrade to the pro version.

我需要向 AlertDialog 添加一个 CheckBox，这将使应用在用户打开应用时不再显示 AlertDialog.

I need to add a CheckBox to the AlertDialog that will make the app no longer show the AlertDialog when the user opens the app.

这是我现在为 AlertDialog 准备的:

Here is what I have for the AlertDialog now:

AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle(" MY_TEXT");
    builder.setMessage(" MY_TEXT ")
           .setCancelable(false)
           .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
               public void onClick(DialogInterface dialog, int id) {
                   Uri uri = Uri.parse("market://details?id=MY_APP_PACKAGE");
                   Intent intent = new Intent (Intent.ACTION_VIEW, uri);
                   startActivity(intent);                          }
           })
           .setNegativeButton("No", new DialogInterface.OnClickListener() {
               public void onClick(DialogInterface dialog, int id) {
                    dialog.cancel();
               }
           }).show();

如何将 CheckBox 添加到 AlertDialog 中，使应用在用户打开应用时不再显示 AlertDialog?

How do I add a CheckBox to the AlertDialog that will make the app no longer show the AlertDialog when the user opens the app?

推荐答案

您必须在 AlertDialog.Builder 对象上使用方法 setView(View).这会将传入的 View 放在消息区域和按钮之间.只需使用 CheckBox 填充 View 并将其传入.这是一个示例:

You have to use the method setView(View) on the AlertDialog.Builder object. This will put the passed in View between the message area and buttons. Simply inflate a View with a CheckBox and pass that in. Here's an example:

checkbox.xml

checkbox.xml

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

    <CheckBox
        android:id="@+id/checkbox"
        style="?android:attr/textAppearanceMedium"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="5dp" />

</FrameLayout>

活动中的代码

View checkBoxView = View.inflate(this, R.layout.checkbox, null);
CheckBox checkBox = (CheckBox) checkBoxView.findViewById(R.id.checkbox);
checkBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {

    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

        // Save to shared preferences
    }
});
checkBox.setText("Text to the right of the check box.");

AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle(" MY_TEXT");
    builder.setMessage(" MY_TEXT ")
           .setView(checkBoxView)
           .setCancelable(false)
           .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
               public void onClick(DialogInterface dialog, int id) {
                   Uri uri = Uri.parse("market://details?id=MY_APP_PACKAGE");
                   Intent intent = new Intent (Intent.ACTION_VIEW, uri); 
                   startActivity(intent);                          }
           })
           .setNegativeButton("No", new DialogInterface.OnClickListener() {
               public void onClick(DialogInterface dialog, int id) {
                    dialog.cancel();
               }
           }).show();
