自定义AlertDialog提示框

因项目需要，大部分情况下需要自定义Dialog来满足项目需求，系统虽然也有，但是界面美观方面，不忍直视。

下面贴出项目中使用的自定义Dialog提示框代码，附：效果图。

必要的两个xml文件，这个是dialog.xml文件：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="@dimen/dialog_width"    android:layout_height="wrap_content"    android:orientation="vertical" >    <TextView        android:id="@+id/text_title"        android:layout_width="match_parent"        android:layout_height="@dimen/header_height"        android:background="@color/main_color"        android:gravity="center"        android:textColor="#ffffff"        android:textSize="20sp" />    <FrameLayout        android:id="@+id/layout_content"        android:layout_width="match_parent"        android:layout_height="wrap_content" >        <TextView            android:id="@+id/text_message"            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:padding="8dp"            android:textColor="@color/main_text_color"            android:textSize="18sp"            android:visibility="gone" />        <ListView            android:id="@+id/list"            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:cacheColorHint="@color/transparent"            android:divider="@drawable/point"            android:listSelector="@drawable/list_selector"            android:visibility="gone" />    </FrameLayout>    <View        android:layout_width="match_parent"        android:layout_height="1px"        android:background="#adadad" />    <LinearLayout        android:id="@+id/layout_footer"        android:layout_width="match_parent"        android:layout_height="wrap_content" >        <Button            android:id="@+id/button_positive"            android:layout_width="match_parent"            android:layout_height="45dp"            android:layout_weight="1.0"            android:background="@drawable/button_common_selector"            android:visibility="gone" />        <View            android:id="@+id/view_line_left"            android:layout_width="1px"            android:layout_height="match_parent"            android:background="#adadad"            android:visibility="visible" />        <Button            android:id="@+id/button_nuetral"            android:layout_width="match_parent"            android:layout_height="45dp"            android:layout_weight="1.0"            android:background="@drawable/button_common_selector"            android:visibility="gone" />        <View            android:id="@+id/view_line_right"            android:layout_width="1px"            android:layout_height="match_parent"            android:background="#adadad"            android:visibility="visible" />        <Button            android:id="@+id/button_negative"            android:layout_width="match_parent"            android:layout_height="45dp"            android:layout_weight="1.0"            android:background="@drawable/button_common_selector"            android:visibility="gone" />    </LinearLayout></LinearLayout>

这个是list_item_dialog.xml文件：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="wrap_content">    <CheckedTextView        android:id="@+id/text"        android:layout_width="match_parent"        android:layout_height="@dimen/row_height"        android:checkMark="@drawable/ic_check_selector"        android:duplicateParentState="true"        android:gravity="center_vertical"        android:padding="12dp"        android:textColor="@color/gray"        android:textSize="18dp" /></LinearLayout>

资源文件中的样式属性，这里就不多说了，可以自己设置随意的颜色和样式，或者加上图片。

使用方法(图1)：

final AlertDialog.Builder builder  = new AlertDialog.Builder(getActivity());                builder.setTitle("选择头像来源");                final String[] avatarSources = getResources().getStringArray(R.array.avatar_sources);                builder.setSingleChoiceItems(avatarSources, 0, new DialogInterface.OnClickListener() {                    @Override                    public void onClick(DialogInterface dialog, int which) {                        switch (which) {                            case 0:                                //点击第一个条目                                break;                            case 1://点击第2个条目                                break;                            case 2://点击第3个条目                                break;                            default:                                break;                        }                        dialog.dismiss();                    }                });                builder.show();

使用方法(图2)：

 final AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());                builder.setTitle("提示");                builder.setMessage("您确定要退出登录么？");                builder.setNegativeButton("取消", null);                builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {                    @Override                    public void onClick(DialogInterface dialog, int which) {                        //退出需要执行的操作                    }                });                builder.show();
