在 AlertDialog 中添加自定义布局 [英] Adding custom layout in an AlertDialog

问题描述

如何使用我的 xml 作为对话框的布局?该类用于显示对话框，但问题是我想设置自己的布局.

How to I use my xml as a layout for my dialog? This class is used to show a dialog but the problem is i want to set my own layout.

 public static void showRateDialog(final Context mContext, final SharedPreferences.Editor editor) {
    final Dialog dialog = new Dialog(mContext);
    dialog.setTitle("Rate " + APP_TITLE);

    LinearLayout ll = new LinearLayout(mContext);
    ll.setOrientation(LinearLayout.VERTICAL);

    TextView tv = new TextView(mContext);
    tv.setText("If you enjoy using " + APP_TITLE + ", please take a moment to rate it. Thanks for your support!");
    tv.setWidth(240);
    tv.setPadding(4, 0, 4, 10);
    ll.addView(tv);

    Button b1 = new Button(mContext);
    b1.setText("Rate " + APP_TITLE);
    b1.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            mContext.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + APP_PNAME)));
            dialog.dismiss();
        }
    });
    ll.addView(b1);

    Button b2 = new Button(mContext);
    b2.setText("Remind me later");
    b2.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            dialog.dismiss();
        }
    });
    ll.addView(b2);

    Button b3 = new Button(mContext);
    b3.setText("No, thanks");
    b3.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            if (editor != null) {
                editor.putBoolean("dontshowagain", true);
                editor.commit();
            }
            dialog.dismiss();
        }
    });
    ll.addView(b3);

    dialog.setContentView(ll);
    dialog.show();
}

我希望它有 3 个按钮和一张图片.可以这样做吗?

I want it to have 3 buttons and a picture. Is it possible to do so?

推荐答案

您可以为对话框设置自定义布局，如下所示:

You can set custom layout to your dialog like below:

创建自定义布局文件:

custom.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

<TextView
    android:id="@+id/text1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:textColor="#FFF" />

<TextView
    android:id="@+id/text2"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:textColor="#FFF"/>

</RelativeLayout>

然后在您的活动中:

// custom dialog
final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.custom);
dialog.setTitle("Title");

// set the custom dialog components - text, image and button
TextView text = (TextView) dialog.findViewById(R.id.text1);
text.setText("Text view 1");

TextView text = (TextView) dialog.findViewById(R.id.text2);
text.setText("Text view 2");
dialog.show();
