android弹出框

阅读更多不得不说，android自带的弹出框真心丑，而且还不好用，接下来介绍几种自定义的弹出框，并且源码防到附件里面。

Android的弹框按照我的理解，至少有两种，一种是自己写个弹框，继承Dialog借口，一种是写一个非全屏的Activity，样式上来讲，应该是后者更好看一些吧。
上面直接上代码:
dialog_normal_layout.xml

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

style.xml

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

package com.example.privatedialog;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;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.message)).removeAllViews();((LinearLayout) layout.findViewById(R.id.message)).addView(contentView, new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));}dialog.setContentView(layout);return dialog;}}}

使用 :

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();
