1. 自定义MyDialog 继承Dialog

在构造方法中引用自定义属性( super(context, R.style.MyDialog);)

public class public class MyDialog extends Dialog {
    private String title;
    private OnOkListener onOkListener;

    public MyDialog(Context context, OnOkListener onOkListener) {
        super(context, R.style.MyDialog);
        this.onOkListener = onOkListener;
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.item_dialog_exit);
        TextView tv_itemdialog_ok = (TextView) findViewById((R.id.tv_itemdialog_ok));
        TextView tv_itemdialog_close = (TextView) findViewById((R.id.tv_itemdialog_close));
        tv_itemdialog_close.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dismiss();
            }
        });
        tv_itemdialog_ok.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dismiss();
                onOkListener.okListener();
            }
        });
    }
}

2. 自定义属性 去除黑色背景

 <style name="MyDialog">
        <item name="android:windowFrame">@null</item>
        <item name="android:windowBackground">@android:color/transparent</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:windowContentOverlay">@null</item>
    </style>

3. dialog布局文件

<?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"
    android:gravity="center"
    android:orientation="vertical">

    <LinearLayout
        android:layout_width="@dimen/x280"
        android:layout_height="wrap_content"
        android:background="@color/green3"
        android:orientation="vertical">

        <TextView
            android:id="@+id/tv_itemdialog_title"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:padding="@dimen/y15"
            android:text="当前正在面聊,是否确定退出?"
            android:textColor="@color/green1"
            android:textSize="@dimen/x16" />

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="@dimen/y5">

            <TextView
                android:id="@+id/tv_itemdialog_ok"
                android:layout_width="@dimen/x100"
                android:layout_height="wrap_content"
                android:layout_marginLeft="@dimen/y20"
                android:background="@drawable/selector_btn_square"
                android:gravity="center"
                android:padding="@dimen/y1"
                android:text="确定"
                android:textColor="@color/bg_White"
                android:textSize="@dimen/x16" />

            <TextView
                android:id="@+id/tv_itemdialog_close"
                android:layout_width="@dimen/x100"
                android:layout_height="wrap_content"
                android:layout_alignParentRight="true"
                android:layout_marginRight="@dimen/y20"
                android:background="@drawable/selector_btn_square"
                android:gravity="center"
                android:padding="@dimen/y1"
                android:text="取消"
                android:textColor="@color/bg_White"
                android:textSize="@dimen/x16" />
        </RelativeLayout>

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="@dimen/y10"/>
    </LinearLayout>
</LinearLayout>
