Builder设计模式设置自定义Dialog

来源:互联网 发布:如何更改默认移动数据 编辑:程序博客网 时间:2024/03/29 20:21

看了一个学习视频看到Dialog原来可以自己自定义模样的哈一个类就可以搞定,做个继承Dialog,自己内部设置一个静态类再加以设计就OK,后来在这个博客中发现这个博主写的很详细果断转:http://blog.csdn.net/duanyanrui/article/details/8494767

注意:Builder中set的时候,要返回文本对象,就像:

 public Builder setMessage(int message) {              this.message = (String) context.getText(message);              return this;          } 


实现机制

1.先自定义一个弹出框的样式

2.自己实现CustomDialog类,继承自Dialog,实现里面方法,在里面加载自定义样式的弹出框;

3.使用时,与使用Dialog一样

dialog_normal_layout.xml样式文件

<?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:layout_width="fill_parent"        android:layout_height="wrap_content"        android:layout_gravity="center"        android:background="@drawable/bg_bombbox"        android:orientation="vertical" >        <TextView            android:id="@+id/title"            style="@style/text_18_ffffff"            android:layout_width="fill_parent"            android:layout_height="40.0dip"            android:gravity="center"            android:text="@string/title_alert"            android:visibility="visible" />        <LinearLayout            android:id="@+id/content"            android:layout_width="fill_parent"            android:layout_height="wrap_content"            android:gravity="center" >            <TextView                android:id="@+id/message"                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" />        </LinearLayout>        <View            android:layout_width="fill_parent"            android:layout_height="1.0px"            android:background="#ffd0d0d0" />        <LinearLayout            android:layout_width="fill_parent"            android:layout_height="60.0dip"            android:layout_gravity="bottom"            android:background="@drawable/dialog_bottom_bg"            android:gravity="center"            android:orientation="horizontal" >            <Button                android:id="@+id/positiveButton"                style="@style/text_15_ffffff_sdw"                android:layout_width="114.0dip"                android:layout_height="40.0dip"                android:background="@drawable/btn_ok_selector"                android:gravity="center"                android:text="@string/ok" />            <Button                android:id="@+id/negativeButton"                style="@style/text_15_666666_sdw"                android:layout_width="114.0dip"                android:layout_height="40.0dip"                android:layout_marginLeft="20.0dip"                android:background="@drawable/btn_cancel_selector"                android:gravity="center"                android:text="@string/cancel" />        </LinearLayout>    </LinearLayout></FrameLayout>

其中引用的样式文件styles.xml

<?xml version="1.0" encoding="utf-8"?><resources xmlns:android="http://schemas.android.com/apk/res/android">    <style name="AppBaseTheme" parent="android:Theme.Light"></style>    <style name="AppTheme" parent="AppBaseTheme"></style>    <style name="text_18_ffffff">        <item name="android:textSize">18.0dip</item>        <item name="android:textColor">#ffffffff</item>    </style>    <style name="text_16_666666">        <item name="android:textSize">16.0dip</item>        <item name="android:textColor">#ff666666</item>    </style>    <style name="sdw_white">        <item name="android:shadowColor">#7fffffff</item>        <item name="android:shadowDx">0.0</item>        <item name="android:shadowDy">0.65</item>        <item name="android:shadowRadius">1.0</item>    </style>    <style name="sdw_79351b">        <item name="android:shadowColor">#ff79351b</item>        <item name="android:shadowDx">0.0</item>        <item name="android:shadowDy">1.0</item>        <item name="android:shadowRadius">1.0</item>    </style>    <style name="text_15_ffffff_sdw" parent="@style/sdw_79351b">        <item name="android:textSize">15.0dip</item>        <item name="android:textColor">#ffffffff</item>    </style>    <style name="text_15_666666_sdw" parent="@style/sdw_white">        <item name="android:textSize">15.0dip</item>        <item name="android:textColor">#ff666666</item>    </style>    <style name="Dialog" parent="android:style/Theme.Dialog">        <item name="android:background">#00000000</item>        <item name="android:windowBackground">@android:color/transparent</item>        <item name="android:windowNoTitle">true</item>        <item name="android:windowIsFloating">true</item>    </style></resources>

自定义Dialog的实现类CustomDialog

package com.dyr.custom;import android.app.Dialog;import android.content.Context;import android.content.DialogInterface;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup.LayoutParams;import android.widget.Button;import android.widget.LinearLayout;import android.widget.TextView;import com.dyr.view.R;public class CustomDialog extends Dialog {public CustomDialog(Context context) {super(context);}public CustomDialog(Context context, int theme) {super(context, theme);}public static class Builder {private Context context;private String title;private String message;private String positiveButtonText;private String negativeButtonText;private View contentView;private DialogInterface.OnClickListener positiveButtonClickListener;private DialogInterface.OnClickListener negativeButtonClickListener;public Builder(Context context) {this.context = context;}public Builder setMessage(String message) {this.message = message;return this;}/** * Set the Dialog message from resource *  * @param title * @return */public Builder setMessage(int message) {this.message = (String) context.getText(message);return this;}/** * Set the Dialog title from resource *  * @param title * @return */public Builder setTitle(int title) {this.title = (String) context.getText(title);return this;}/** * Set the Dialog title from String *  * @param title * @return */public Builder setTitle(String title) {this.title = title;return this;}public Builder setContentView(View v) {this.contentView = v;return this;}/** * Set the positive button resource and it's listener *  * @param positiveButtonText * @return */public Builder setPositiveButton(int positiveButtonText,DialogInterface.OnClickListener listener) {this.positiveButtonText = (String) context.getText(positiveButtonText);this.positiveButtonClickListener = listener;return this;}public Builder setPositiveButton(String positiveButtonText,DialogInterface.OnClickListener listener) {this.positiveButtonText = positiveButtonText;this.positiveButtonClickListener = listener;return this;}public Builder setNegativeButton(int negativeButtonText,DialogInterface.OnClickListener listener) {this.negativeButtonText = (String) context.getText(negativeButtonText);this.negativeButtonClickListener = listener;return this;}public Builder setNegativeButton(String negativeButtonText,DialogInterface.OnClickListener listener) {this.negativeButtonText = negativeButtonText;this.negativeButtonClickListener = listener;return this;}public CustomDialog create() {LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);// instantiate the dialog with the custom Themefinal CustomDialog dialog = new CustomDialog(context,R.style.Dialog);View layout = inflater.inflate(R.layout.dialog_normal_layout, null);dialog.addContentView(layout, new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));// set the dialog title((TextView) layout.findViewById(R.id.title)).setText(title);// set the confirm buttonif (positiveButtonText != null) {((Button) layout.findViewById(R.id.positiveButton)).setText(positiveButtonText);if (positiveButtonClickListener != null) {((Button) layout.findViewById(R.id.positiveButton)).setOnClickListener(new View.OnClickListener() {public void onClick(View v) {positiveButtonClickListener.onClick(dialog,DialogInterface.BUTTON_POSITIVE);}});}} else {// if no confirm button just set the visibility to GONElayout.findViewById(R.id.positiveButton).setVisibility(View.GONE);}// set the cancel buttonif (negativeButtonText != null) {((Button) layout.findViewById(R.id.negativeButton)).setText(negativeButtonText);if (negativeButtonClickListener != null) {((Button) layout.findViewById(R.id.negativeButton)).setOnClickListener(new View.OnClickListener() {public void onClick(View v) {negativeButtonClickListener.onClick(dialog,DialogInterface.BUTTON_NEGATIVE);}});}} else {// if no confirm button just set the visibility to GONElayout.findViewById(R.id.negativeButton).setVisibility(View.GONE);}// set the content messageif (message != null) {((TextView) layout.findViewById(R.id.message)).setText(message);} else if (contentView != null) {// if no message set// add the contentView to the dialog body((LinearLayout) layout.findViewById(R.id.content)).removeAllViews();((LinearLayout) layout.findViewById(R.id.content)).addView(contentView, new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT));}dialog.setContentView(layout);return dialog;}}}

使用代码

CustomDialog.Builder builder = new CustomDialog.Builder(this);builder.setMessage("这个就是自定义的提示框");builder.setTitle("提示");builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {public void onClick(DialogInterface dialog, int which) {dialog.dismiss();//设置你的操作事项}});builder.setNegativeButton("取消",new android.content.DialogInterface.OnClickListener() {public void onClick(DialogInterface dialog, int which) {dialog.dismiss();}});builder.create().show();
