android自定义弹出框样式实现
前言:
做项目时,感觉Android自带的弹出框样式比较丑,很多应用都是自己做的弹出框,这里也试着自己做了一个。
废话不说先上图片:

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
具体代码
dialog_normal_layout.xml样式文件
- <?xml version="1.0" encoding="utf-8"?>

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) {

- .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 Theme
- final 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 button
- if (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 GONE
- layout.findViewById(R.id.positiveButton).setVisibility(
- View.GONE);
- }
- // set the cancel button
- if (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 GONE
- layout.findViewById(R.id.negativeButton).setVisibility(
- View.GONE);
- }
- // set the content message
- if (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();
至此,自定义弹出框已经完成,是不是感觉很简单呢。
