Android自定义dialog版本更新

这个对话框是我在网上找的,自己写有点难看,没办法没有艺术细胞。我改了一点让它能显示更多内容,增加了一个参数,刚好用在正在写的APP上面,配合异步下载简直完美。

Android自定义dialog版本更新

这款对话框有两种模式,一种有两种按钮,可以取消,一直只有一个按钮,强行升级。下面是构建方法。

dialog布局xml文件代码

styles配置信息,添加在你的styles文件中。

<style name="text_18_ffffff">
    <item name="android:textSize">18.0dip</item>
    <item name="android:textColor">#777733</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>

然后新建一个类,继承dialog,代码如下

package com.zdhcsc.jingmizujian.hl;

import android.app.Dialog;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.LinearLayout;
import android.widget.TextView;

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 String message,title;
        private View contentView;
        private String positiveButtonText;
        private String negativeButtonText;
        private String singleButtonText;
        private View.OnClickListener positiveButtonClickListener;
        private View.OnClickListener negativeButtonClickListener;
        private View.OnClickListener singleButtonClickListener;

        private View layout;
        private CustomDialog dialog;
        public Builder(Context context) {
            //这里传入自定义的style,直接影响此Dialog的显示效果。style具体实现见style.xml
            dialog = new CustomDialog(context, R.style.Dialog);
            LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            layout = inflater.inflate(R.layout.upapp_layout, null);
            dialog.addContentView(layout, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
        }

        public Builder setMessage(String message) {
            this.message = message;
            return this;
        }
        public Builder settitle(String title) {
            this.title = title;
            return this;
        }
        public Builder setContentView(View v) {
            this.contentView = v;
            return this;
        }

        public Builder setPositiveButton(String positiveButtonText, View.OnClickListener listener) {
            this.positiveButtonText = positiveButtonText;
            this.positiveButtonClickListener = listener;
            return this;
        }

        public Builder setNegativeButton(String negativeButtonText, View.OnClickListener listener) {
            this.negativeButtonText = negativeButtonText;
            this.negativeButtonClickListener = listener;
            return this;
        }

        public Builder setSingleButton(String singleButtonText, View.OnClickListener listener) {
            this.singleButtonText = singleButtonText;
            this.singleButtonClickListener = listener;
            return this;
        }

        /**
         * 创建单按钮对话框
         * @return
         */
        public CustomDialog createSingleButtonDialog() {
            showSingleButton();
            layout.findViewById(R.id.singleButton).setOnClickListener(singleButtonClickListener);
            //如果传入的按钮文字为空,则使用默认的“返回”
            if (singleButtonText != null) {
                ((Button) layout.findViewById(R.id.singleButton)).setText(singleButtonText);
            } else {
                ((Button) layout.findViewById(R.id.singleButton)).setText("返回");
            }
            create();
            return dialog;
        }

        /**
         * 创建双按钮对话框
         * @return
         */
        public CustomDialog createTwoButtonDialog() {
            showTwoButton();
            layout.findViewById(R.id.positiveButton).setOnClickListener(positiveButtonClickListener);
            layout.findViewById(R.id.negativeButton).setOnClickListener(negativeButtonClickListener);
            //如果传入的按钮文字为空,则使用默认的“是”和“否”
            if (positiveButtonText != null) {
                ((Button) layout.findViewById(R.id.positiveButton)).setText(positiveButtonText);
            } else {
                ((Button) layout.findViewById(R.id.positiveButton)).setText("是");
            }
            if (negativeButtonText != null) {
                ((Button) layout.findViewById(R.id.negativeButton)).setText(negativeButtonText);
            } else {
                ((Button) layout.findViewById(R.id.negativeButton)).setText("否");
            }
            create();
            return dialog;
        }

        /**
         * 单按钮对话框和双按钮对话框的公共部分在这里设置
         */
        private void create() {
            if(title!=null){
                ((TextView) layout.findViewById(R.id.title_updata)).setText(title);
            }
            if (message != null) {      //设置提示内容
                ((TextView) layout.findViewById(R.id.message)).setText(message);
            } else if (contentView != null) {       //如果使用Builder的setContentview()方法传入了布局,则使用传入的布局
                ((LinearLayout) layout.findViewById(R.id.content)).removeAllViews();
                ((LinearLayout) layout.findViewById(R.id.content))
                        .addView(contentView, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
            }
            dialog.setContentView(layout);
            dialog.setCancelable(true);     //用户可以点击手机Back键取消对话框显示
            dialog.setCanceledOnTouchOutside(false);        //用户不能通过点击对话框之外的地方取消对话框显示
        }

        /**
         * 显示双按钮布局,隐藏单按钮
         */
        private void showTwoButton() {
            layout.findViewById(R.id.singleButtonLayout).setVisibility(View.GONE);
            layout.findViewById(R.id.twoButtonLayout).setVisibility(View.VISIBLE);
        }

        /**
         * 显示单按钮布局,隐藏双按钮
         */
        private void showSingleButton() {
            layout.findViewById(R.id.singleButtonLayout).setVisibility(View.VISIBLE);
            layout.findViewById(R.id.twoButtonLayout).setVisibility(View.GONE);
        }

    }
}

然后在要使用的代码中声明,为方便使用,建议声明为全局变量

private CustomDialog.Builder builder;
private CustomDialog mDialog;

然后再为两种模式分别构建方法

一个按钮

private void showSingleButtonDialog(String title,String alertText, String btnText, View.OnClickListener onClickListener) {
    mDialog = builder.setMessage(alertText)
            .settitle(title)
            .setSingleButton(btnText, onClickListener)
            .createSingleButtonDialog();
    mDialog.show();
}

两个按钮

private void showTwoButtonDialog(String title, String alertText, String confirmText, String cancelText, View.OnClickListener conFirmListener, View.OnClickListener cancelListener) {
    mDialog = builder.setMessage(alertText)
            .settitle(title)
            .setPositiveButton(confirmText, conFirmListener)
            .setNegativeButton(cancelText, cancelListener)
            .createTwoButtonDialog();
    mDialog.show();
}

使用一个按钮

showSingleButtonDialog("标题", "内容", "按钮名字", new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        mDialog.dismiss();
        //这里写自定义处理XXX
    }
});

使用两个按钮

showTwoButtonDialog("标题","内容", "确定", "取消", new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        mDialog.dismiss();
 //这里写自定义处理XXX
}
});

感觉很棒!可以赞赏支持我哟~
