android studio 单选对话框或多选对话框的实现

要在Android Studio中实现单选对话框或多选对话框，可以使用AlertDialog.Builder类。下面是实现单选对话框和多选对话框的代码示例：

单选对话框：

AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle("选择项");
builder.setSingleChoiceItems(items, checkedItem, new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        // 处理选中项的逻辑
    }
});
builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        // 处理确定按钮点击事件的逻辑
    }
});
builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        // 处理取消按钮点击事件的逻辑
    }
});
AlertDialog dialog = builder.create();
dialog.show();

多选对话框：

AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle("选择项");
builder.setMultiChoiceItems(items, checkedItems, new DialogInterface.OnMultiChoiceClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which, boolean isChecked) {
        // 处理选中项的逻辑
    }
});
builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        // 处理确定按钮点击事件的逻辑
    }
});
builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        // 处理取消按钮点击事件的逻辑
    }
});
AlertDialog dialog = builder.create();
dialog.show();
