Android之自定义Dialog弹出框公共组件类

        因为刚进新公司，手上暂时没项目，于是Q哥就说让我写个自定义的弹出框公共组件类，方便以后项目中可以直接调用。于是我首先上网查了下这方面的资料，自定义dialog的信息是有不少，但没有一个是我想要的。我想实现的是可以在调用时直接传参数就能定义Dialog的背景、title背景、内容背景、button背景、字体颜色、大小等等这些，于是就只好自己想着写了，最后基本算是达到了预想的效果，但同时却感觉调用时没有预先想的那么清晰便捷，可能是因为参数多了以后，人容易晕吧。但是不管怎样，本着知识共享，共同进步的精神，就把这东西写出来，一方便是做一个知识总结，另一方面也希望给需要用到的朋友带来些帮助吧、、

一：先说下思路

1. android 系统提供了一个 Dialog类. 我们通过重写Dialog,可以把自己的工作放在"protected void onCreate(Bundle savedInstanceState)" 在里面先调用系统的"super.onCreate(savedInstanceState)" 其就会保证调用这个method. 
2. 至于 Dialog 的界面 我们就通过自己写一个xml 文件 然后 在 "void onCreate(Bundle)" 通过 "setContentView()" 来使之生效

3. 然后我们通过构造函数，把想自定义的内容构造出来，在调用的时候直接传参数就行了 

3. Dialog 使用问题： 1. 弹出：show() 2. 取消：dismiss() 

二：自定义的xml布局

<?xml version="1.0" encoding="utf-8"?>

    android:layout_height="fill_parent"

三：自定义Dialog类

import android.graphics.Color;
import com.dyr.view.R;
import android.R.integer;
import android.app.Dialog;
import android.content.Context;
import android.content.res.ColorStateList;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.LinearLayout;
import android.widget.TextView;

public class DialogDemo extends Dialog implements android.view.View.OnClickListener {
    LinearLayout layout, layoutTitleView, layoutBodyView, layoutFootView;
    TextView Dlg_title, Dlg_Content;
    View lineView, lineView1;
    Button Dlg_Yes, Dlg_No;
    CustomDialogListener cdListener;
    String title, content;
    int titleColor;
    String titleColorStr;// 标题颜色
    int layoutTitleViewBg;// 标题背景色
    int layoutBodyViewBg;//内容背景色
    int layoutFootViewBg;//底部背景色
    int Dlg_Yes_Bg,Dlg_No_Bg; //两个button的背景色
    int lineViewColorStr, lineView1ColorStr;
    int contentColor;//内容字体颜色
    Float titleSize;
    int allLayoutBg, layoutTitleColor; //背景
    public Context ctx;
    public DialogDemo(Context context,
                      int theme,

                      int layoutTitleViewBg,
                      int layoutBodyViewBg,
                      int layoutFootViewBg,
                      String title,
                      int titleColor,
                      Float titleSize,
                      int lineViewColorStr,
                      int lineView1ColorStr,
                      String content,
                      int contentColor,
                      int Dlg_Yes_Bg,
                      int Dlg_No_Bg,
                      CustomDialogListener cdListener) {
        super(context, theme);
        this.cdListener = cdListener;
        //       this.allLayoutBg = allLayoutBg;
        this.layoutTitleColor = layoutTitleColor;
        this.layoutTitleViewBg=layoutTitleViewBg;
        this.layoutBodyViewBg=layoutBodyViewBg;
        this.layoutFootViewBg=layoutFootViewBg;
        this.title = title;
        this.titleColor = titleColor;
        this.titleSize = titleSize;
        this.lineViewColorStr = lineViewColorStr;
        this.lineView1ColorStr = lineView1ColorStr;
        this.content = content;
        this.contentColor = contentColor;
        this.Dlg_Yes_Bg=Dlg_Yes_Bg;
        this.Dlg_No_Bg=Dlg_No_Bg;
        this.ctx = context;
    }

    public DialogDemo(Context context,
                      int theme,
                      int allLayoutBg,
//			int layoutTitleColor ,
                      String title,
                      String titleColor,
                      Float titleSize,
                      String content,
                      int contentColor,
                      CustomDialogListener cdListener) {
        super(context, theme);
        this.cdListener = cdListener;
        this.allLayoutBg = allLayoutBg;
        this.layoutTitleColor = layoutTitleColor;
        this.title = title;
        this.titleColorStr = titleColor;
        this.titleSize = titleSize;
        this.content = content;
        this.contentColor = contentColor;
//      this.context=context;
    }


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        this.setContentView(R.layout.exit_dialog);
        this.setCanceledOnTouchOutside(false); //点击外部不会消失  
        InitViews();
    }

    private void InitViews() {

        layoutTitleView=(LinearLayout)findViewById(R.id.layoutTitleView);
        layoutBodyView=(LinearLayout)findViewById(R.id.layoutBodyView);
        layoutFootView=(LinearLayout)findViewById(R.id.layoutFootView);
        Dlg_title = (TextView) findViewById(R.id.Dlg_Title);
        lineView = (View) findViewById(R.id.lineView);
        lineView1 = (View) findViewById(R.id.lineView1);
        Dlg_Content = (TextView) findViewById(R.id.Dlg_content);

//      layout.setBackgroundResource(this.allLayoutBg);
        layoutTitleView.setBackgroundResource(this.layoutTitleViewBg);
        layoutBodyView.setBackgroundResource(this.layoutBodyViewBg);
        layoutFootView.setBackgroundResource(this.layoutFootViewBg);


        Dlg_title.setText(this.title);
        Dlg_title.setTextColor(this.titleColor);
//      Dlg_title.setTextColor(Color.parseColor(titleColorStr));
        lineView.setBackgroundColor(this.lineViewColorStr);
        lineView1.setBackgroundColor(this.lineView1ColorStr);
        Dlg_title.setTextSize(this.titleSize);
        Dlg_Content.setText(this.content);
        Dlg_Content.setTextColor(contentColor);

        Dlg_Yes = (Button) findViewById(R.id.Dlg_Yes);
        Dlg_No = (Button) findViewById(R.id.Dlg_No);
        Dlg_Yes.setBackgroundResource(this.Dlg_Yes_Bg);
        Dlg_No.setBackgroundResource(this.Dlg_No_Bg);
        Dlg_Yes.setOnClickListener(this);
        Dlg_No.setOnClickListener(this);
    }

    public void setTitleColor(int color) {
        Dlg_title.setTextColor(color);
    }

    @Override
    public void onClick(View v) {
        cdListener.OnClick(v);
        dismiss();

    }

    @Override
    public void dismiss() {
        System.out.println("dialog dismiss...");
        super.dismiss();
    }
}

四：接口类CustomDialogListener

import android.view.View;
public interface CustomDialogListener {
	 public void OnClick(View view); 
}

五：调用方法

DialogDemo dialog=new DialogDemo(MainActivity.this,
			R.style.Dialog,
                        R.drawable.dialog_titleview_bg,    //设置title框的背景
                        R.drawable.dialog_bodyview_bg,    //设置body框的背景
                        R.drawable.dialog_footview_bg,   //设置foot框的背景
			"自定义Dialog标题",              //设置标题
                        getResources().getColor(R.color.red),//设置标题颜色
			(float) 21,                         //设置标题字体
                        getResources().getColor(R.color.red), //设置上分割线
                        getResources().getColor(R.color.red) ,//设置下分割线
			"此处显示内容~~~~~~~~\n",          //内容
			YELLOW,                              //内容字体颜色
                        R.drawable.btn_ok_pressed,          //设置okbutton背景色
                        R.drawable.btn_cancel_pressed,          //设置nobutton背景色
			new CustomDialogListener() {         //设置按钮监  
		            public void OnClick(View view) { 
		                // TODO Auto-generated method stub  
		                  switch(view.getId()){    
		                     case R.id.Dlg_Yes: 
		                    //    finish(); 
		                         break;    
		                     case R.id.Dlg_No: 
		                        break;    	      
		                 }    
		            } 
		});
		     dialog.show();

六：运行效果图

至此，我们就可以自定义弹出框的样式、颜色、字体、等所有内容了。可能有些地方做的不好，希望大牛们多多交流~
