AlertDialog-Fast-Styling

Some visual parts of android.support.v7.AlertDialog can be fastly styled by inheriting its base theme instead of customizing new layouts, which is considered clumsy. Modifying these visual parts still agrees with Material Design.

Requirement

  dependencies {
      compile 'com.android.support:appcompat-v7:22.2.0'
  }

Approach

1. Fork the following style xml code into your styles.xml and modify their value as you want.

   <style name="AlertDialogFastStyling" parent="Theme.AppCompat.Light.Dialog.Alert"> @color/abc_primary_text_material_light @style/AlertDialogFastStyling.Title @drawable/abc_dialog_material_background_light 24dp 24dp @style/AlertDialogFastStyling.Button @drawable/abc_btn_radio_material @drawable/abc_btn_check_material </style>

    <style name="AlertDialogFastStyling.Title" parent="RtlOverlay.DialogWindowTitle.AppCompat">
        <item name="android:textAppearance">@style/AlertDialogFastStyling.Title.TextAppearance</item>
    </style>
    <style name="AlertDialogFastStyling.Title.TextAppearance">
        <item name="android:textSize">@dimen/abc_text_size_title_material</item>
        <item name="android:textColor">@color/abc_primary_text_material_light</item>
    </style>
    <style name="AlertDialogFastStyling.Button" parent="Widget.AppCompat.Button.ButtonBar.AlertDialog">
        <item name="android:textColor">#009688</item>
        <item name="android:textSize">14sp</item>
    </style>
   

2. Use AlertDialogFastStyling while building AlertDialog component. The following samples are available for testing and their insets show the visual mappings to style items in AlertDialogFastStyling.

Confirm Dialog

    AlertDialog dialog = new AlertDialog.Builder(context, R.style.AlertDialogFastStyling)
            .setTitle("提醒")
            .setPositiveButton("是", null)
            .setNegativeButton("否", null)
            .setMessage("检测到距离您上次清理已超过30天，是否立即清理？")
            .show();

Choice Dialog

    AlertDialog dialog = new AlertDialog.Builder(context, R.style.AlertDialogFastStyling)
            .setItems(new String[] {"布丁味的老人茶", "奶昔", "巴拿拿牌烤香蕉"},
                    new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            dialog.cancel();
                        }
            })
            .show();

Radio Dialog

    AlertDialog dialog = new AlertDialog.Builder(context, R.style.AlertDialogFastStyling)
            .setSingleChoiceItems(new String[] {"布丁味的老人茶", "奶昔", "巴拿拿牌烤香蕉"}, 0, null)
            .setPositiveButton("确定", null)
            .setNegativeButton("取消", null)
            .show();

Check Dialog

    AlertDialog dialog = new AlertDialog.Builder(context, R.style.AlertDialogFastStyling)
            .setMultiChoiceItems(new String[] {"布丁味的老人茶", "奶昔", "巴拿拿牌烤香蕉"},
                    new boolean[] {false, true, true},
                    null)
            .setPositiveButton("确定", null)
            .setNegativeButton("取消", null)
            .show();
