使用CheckBox的AlertDialog

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("选择你喜欢的水果");

final String[] fruits = {"苹果", "香蕉", "橙子", "葡萄"};
final boolean[] checkedFruits = {false, false, false, false};

builder.setMultiChoiceItems(fruits, checkedFruits, new DialogInterface.OnMultiChoiceClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which, boolean isChecked) {
        checkedFruits[which] = isChecked;
    }
});

builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < checkedFruits.length; i++) {
            if (checkedFruits[i]) {
                sb.append(fruits[i]).append(", ");
            }
        }
        if (sb.length() > 0) {
            sb.delete(sb.length() - 2, sb.length());
        }
        Toast.makeText(MainActivity.this, "你选择了: " + sb.toString(), Toast.LENGTH_SHORT).show();
    }
});

AlertDialog alertDialog = builder.create();
alertDialog.show();
