Android之自定义Dialog弹出框公共组件类

来源：互联网发布：上海趣骋网络编辑：程序博客网时间：2024/06/03 14:52

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"?><FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:clickable="true"    android:orientation="vertical"    android:padding="20.0dip" >    <LinearLayout        android:id="@+id/All_layout"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:layout_gravity="center"        android:orientation="vertical" >        <!-- title -->        <LinearLayout            android:id="@+id/layoutTitleView"            android:layout_width="fill_parent"            android:layout_height="wrap_content"            android:layout_gravity="center"            android:background="@drawable/dialog_titleview_bg"            android:orientation="horizontal" >            <TextView                android:id="@+id/Dlg_Title"                style="@style/text_18_ffffff"                android:layout_width="fill_parent"                android:layout_height="40.0dip"                android:gravity="center"                android:text="标题"                 android:textColor="#fff"                android:visibility="visible" />        </LinearLayout>        <View            android:id="@+id/lineView"            android:layout_width="fill_parent"            android:layout_height="1.0px"            android:background="#ffd0d0d0" />                <!-- body -->        <LinearLayout            android:id="@+id/layoutBodyView"            android:layout_width="fill_parent"            android:layout_height="wrap_content"            android:layout_gravity="bottom"            android:gravity="center"            android:background="@drawable/dialog_bodyview_bg"            android:orientation="horizontal" >            <TextView                android:id="@+id/Dlg_content"                style="@style/text_16_666666"                android:layout_width="fill_parent"                android:layout_height="wrap_content"                android:gravity="left|center"                android:lineSpacingMultiplier="1.5"                android:minHeight="120.0dip"                android:paddingBottom="15.0dip"                android:paddingLeft="20.0dip"                android:paddingRight="20.0dip"                android:paddingTop="15.0dip"                android:textColor="#fff"                android:text="内容" />        </LinearLayout>        <View            android:id="@+id/lineView1"            android:layout_width="fill_parent"            android:layout_height="1.0px"            android:background="#ffd0d0d0" />        <!-- button -->        <LinearLayout            android:id="@+id/layoutFootView"            android:layout_width="match_parent"            android:layout_height="60.0dip"            android:layout_gravity="bottom"            android:gravity="center"            android:background="@drawable/dialog_footview_bg"            android:orientation="horizontal" >            <Button                android:id="@+id/Dlg_Yes"                android:layout_width="110dp"                android:layout_height="wrap_content"                android:background="@drawable/btn_ok_pressed"                android:gravity="center"                android:text="是"                android:textColor="#fff"                android:textSize="16sp" />            <Button                android:id="@+id/Dlg_No"                android:layout_width="110dp"                android:layout_height="wrap_content"                android:layout_marginLeft="10dp"                android:background="@drawable/btn_ok_normal"                android:gravity="center"                android:text="否"                android:textColor="#fff"                android:textSize="16sp" />        </LinearLayout>    </LinearLayout></FrameLayout>

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~
