如題，當(dāng)你覺得系統(tǒng)給的對話框太丑了，想自己寫時(shí)發(fā)現(xiàn)完全不知道怎么寫，問度娘，又看得一頭霧水，那今天就教你傻瓜式的用別人寫好的吧，怎么實(shí)現(xiàn)的我不管，只要能用就行了
先上圖，你覺得OK就用，不Ok就pass：
兩個(gè)按鈕
一個(gè)按鈕
第一步：
新建文件：
如圖所示在drawable上新建7個(gè)文件
新建7個(gè)resource文件，文件名，這個(gè)很重要，分別叫：
第一個(gè)：background_shape.xml
第一個(gè)代碼：
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<corners android:radius="35dp"/>
<!--設(shè)置背景顏色-->
<solid android:color="#f0f0f0f0"/>
</shape>
第二個(gè)：left_button_shape.xml
第二個(gè)代碼：
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/left_button_shape_depend_resource" android:state_pressed="true"/>
<!--<item android:drawable="@drawable/trans_bg"/>-->
</selector>
第三個(gè)：left_button_shape_depend_resource.xml ?
第三個(gè)代碼：
<?xml version="1.0" encoding="utf-8"?>
<shape android:shape="rectangle"
xmlns:android="http://schemas.android.com/apk/res/android" >
<corners android:bottomLeftRadius="35dp"/>
<!--設(shè)置按鈕點(diǎn)擊時(shí)的顏色-->
<solid android:color="#f0d3d3d3"/>
</shape>
第四個(gè)：right_button_shape.xml
第四個(gè)代碼：
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/right_button_shape_depend_resource" android:state_pressed="true"/>
<!--<item android:drawable="@drawable/trans_bg"/>-->
</selector>
第五個(gè)： right_button_shape_depend_resource.xml
第五個(gè)代碼：
<?xml version="1.0" encoding="utf-8"?>
<shape android:shape="rectangle"
xmlns:android="http://schemas.android.com/apk/res/android" >
<corners android:bottomRightRadius="35dp"/>
<!--設(shè)置按鈕點(diǎn)擊時(shí)的顏色-->
<solid android:color="#f0d3d3d3"/>
</shape>
第六個(gè)：single_button_shape.xml
第六個(gè)代碼：
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/single_button_shape_depend_resource" android:state_pressed="true"/>
<!--<item android:drawable="@drawable/trans_bg"/>-->
</selector>
第七個(gè)：single_button_shape_depend_resource.xml
第七個(gè)代碼：
<?xml version="1.0" encoding="utf-8"?>
<shape android:shape="rectangle"
xmlns:android="http://schemas.android.com/apk/res/android" >
<corners android:bottomLeftRadius="35dp"
android:bottomRightRadius="35dp"/>
<solid android:color="#f0d3d3d3"/>
</shape>
接下來----------------------------------------------------------------------------------------------
還要?jiǎng)?chuàng)建最后一個(gè)xml文件，在values下面創(chuàng)建，如圖：
創(chuàng)建一個(gè)value resource
名稱還是要注意，叫：custom_style.xml
其代碼如下 ：
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="CustomDialog" parent="android:style/Theme.Dialog">
<!--背景顏色及和透明程度-->
<item name="android:windowBackground">@android:color/transparent</item>
<!--是否去除標(biāo)題 -->
<item name="android:windowNoTitle">true</item>
<!--是否去除邊框-->
<item name="android:windowFrame">@null</item>
<!--是否浮現(xiàn)在activity之上-->
<item name="android:windowIsFloating">true</item>
<!--是否模糊-->
<item name="android:backgroundDimEnabled">true</item>
</style>
</resources>
別問我可不可以起其他名，如果你是大佬隨意，是小白還是老老實(shí)實(shí)，可以避免很對問題，聽話不挨打
第二步：
新建一個(gè)Java class，如圖：
新建一個(gè)類名稱為：MyDialog
新建一個(gè)類，類名為：MyDialog，將一下代碼復(fù)制：
import android.app.Dialog;
import android.content.Context;
import android.graphics.Color;
import android.graphics.Typeface;
import android.os.Bundle;
import android.view.Gravity;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.TextView;
/**
* 使用說明：要想改對話框圓角的大小去background_shape.xml里面改，
* 同時(shí)還要到left_button_shape_depend_resource.xml和right_button_shape_depend_resource.xml
* 里面去改，要想改背景顏色也是一樣的
*
* 本類提供方法setTitleSize()改標(biāo)題字號和setMessageSize()改內(nèi)容字號
* setLeft() setRight() setTop() setBottom()四個(gè)方法改內(nèi)容上下左右邊距
* setTitleHeight() setBottomHeight()分別設(shè)置標(biāo)題和底部按鈕的高度
* 其他的想改字體顏色的到代碼里面去看就行了 改標(biāo)題顏色定位到131行代碼
* 內(nèi)容142 按鈕158和171，自行修改，方法就懶得提供了
* 本類一共加載了四次資源，一次是主題，一次是背景，兩次是按鈕，左一個(gè)，右一個(gè)

}
}
第三步：
使用：
使用方法和Android自帶的AlertDialog是一樣的，只是不需要create，直接設(shè)置完標(biāo)題和內(nèi)容，確定和取消，就show就行了，下面是示例：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
new MyDialog(MainActivity.this)
.setTitle("警告")
.setMessage("你確定要?jiǎng)h除該文件嗎?")
.setPositiveButton("是", new View.OnClickListener() {
@Override
public void onClick(View v) {
}
})
.setPositiveButton("否", new View.OnClickListener() {
@Override
public void onClick(View v) {
}
})
.show();
}
