android自定义弹出框样式的实现方法

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"?>
<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"?>

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 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。
