自定义Dialog，仿造别人写的，内容有些不同，完全自己定制

本文介绍如何仿照系统AlertDialog.Builder创建自定义Dialog。通过更改类名为MyDialog.Builder，可以轻松定制个人化的Dialog。关键在于调整XML布局文件ar_shape_dottedrect_message.xml以及应用特定的Dialog样式，更多细节可在作者的其他日志中找到。

仿写系统的AlertDialog.Builder，如需定制自己的Dialog，直接改类名即可，如MyDialog.Builder builder = new MyDialog.Builder();

MyDialog.java

public class MyDialog_Common extends Dialog {

public MyDialog_Common(Context context) {
super(context);

}

public MyDialog_Common(Context context, int theme) {
super(context, theme);
}


public static class Builder {
private Context context;
private View contentView;
//对话框内容
private String dialogPrompte;
//提示信息
private String dialogTitle;
//对话框标题
private int dialogIcon;
//对话框图标
private String dialogMessage;
//对话框信息
private String FirstButtonText;
//第一个按钮
private String SecondButtonText;
//第二个按钮
private String ThirdButtonText;
//第三个按钮
private DialogInterface.OnClickListener FirstButtonListener, SecondButtonListener,ThirdButtonListener;

public Builder(Context context) {
this.context = context;
}

public Builder setContentView(View v) {
this.contentView = v;
return this;
}

public Builder setIcon(int imageID) {
this.dialogIcon = imageID;
return this;
}
public Builder setTitle(String title) {
this.dialogTitle = title;
return this;
}

public Builder setPromote(String promote) {
this.dialogPrompte = promote;
return this;
}
public Builder setTitle(int title) {
this.dialogTitle = context.getString(title);
return this;
}

public Builder setMessage(String message) {
this.dialogMessage = message;
return this;
}

public Builder setMessage(int message) {
this.dialogMessage = context.getString(message);
return this;
}

public Builder setFirstButton(String firstButText,DialogInterface.OnClickListener FirstButtonListener) {
this.FirstButtonText = firstButText;
this.FirstButtonListener = FirstButtonListener;
return this;
}

public Builder setSecondButton(String SecondButtonText, DialogInterface.OnClickListener SecondButtonListener) {
this.SecondButtonText = SecondButtonText;
this.SecondButtonListener = SecondButtonListener;
return this;
}

public Builder setFirstButton(int FirstButtonText,DialogInterface.OnClickListener FirstButtonListener) {
this.FirstButtonText = context.getString(FirstButtonText);
this.FirstButtonListener = FirstButtonListener;
return this;
}

public Builder setSecondButton(int SecondButtonText, DialogInterface.OnClickListener SecondButtonListener) {
this.SecondButtonText = context.getString(SecondButtonText);
this.SecondButtonListener = SecondButtonListener;
return this;
}

public Builder setThirdButton(String ThirdButtonText, DialogInterface.OnClickListener ThirdButtonListener) {
this.ThirdButtonText = ThirdButtonText;
this.ThirdButtonListener = ThirdButtonListener;
return this;
}

ar_shape_dottedrect_message.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">

<stroke android:width="0.5dip" android:color="#7D704B" />
<padding android:left="0dp" android:top="0dp" android:right="0dp" android:bottom="0dp" />
<corners android:radius="13dp" />
    
</shape>

最重要的还是配Dialog样式文件，我的其他日志有配，可参考！
