Android仿IOS UIAlertView对话框

本文实例为大家分享了Android仿IOS UIAlertView对话框的具体代码，供大家参考，具体内容如下

显示效果:

我在参考链接中看到了作者的仿的qq提示框，但是在使用的时候并不是很方面，有一些不足，于是我参照Android系统AlertDialog，使用参考链接中的布局文件和style文件，用自己的方法自定义了一下这个仿IOS上面UIAlertView的效果，这样的话让我们可以想使用系统AlertDialog一样使用我自定义的CustomDialog。

CustomDialog使用代码:

package com.example.iosalertview;

import android.app.Activity;
import android.app.AlertDialog;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

import com.example.iosalertview.CustomDialog.Builder;

public class MainActivity extends Activity implements OnClickListener{
private Button ios_dialog_btn,android_dialog_btn;

@Override
protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);

ios_dialog_btn = (Button) findViewById(R.id.ios_dialog_btn);
 android_dialog_btn = (Button) findViewById(R.id.android_dialog_btn);

ios_dialog_btn.setOnClickListener(this);
 android_dialog_btn.setOnClickListener(this);

}

@Override
public void onClick(View v) {
 switch (v.getId()) {
 case R.id.ios_dialog_btn:
  CustomDialog.Builder builder = new Builder(MainActivity.this);
  builder.setTitle(R.string.prompt);
  builder.setMessage(R.string.exit_app);
  builder.setPositiveButton(R.string.confirm, null);
  builder.setNegativeButton(R.string.cancel, null);
  builder.create().show();
  break;
 case R.id.android_dialog_btn:
  AlertDialog.Builder mbuilder = new AlertDialog.Builder(MainActivity.this);
  mbuilder.setTitle(R.string.prompt);
  mbuilder.setMessage(R.string.exit_app);
  mbuilder.setPositiveButton(R.string.confirm, null);
  mbuilder.setNegativeButton(R.string.cancel, null);
  mbuilder.create().show();
  break;

default:
  break;
 }
}

}

自定义CustomDialog代码:

package com.example.iosalertview;

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; //上下文对象
 private String title; //对话框标题
 private String message; //对话框内容
 private String confirm_btnText; //按钮名称“确定”
 private String cancel_btnText; //按钮名称“取消”
 private View contentView; //对话框中间加载的其他布局界面
 /*按钮坚挺事件*/
 private DialogInterface.OnClickListener confirm_btnClickListener;
 private DialogInterface.OnClickListener cancel_btnClickListener;

public Builder(Context context) {
  this.context = context;
 }

/*设置对话框信息*/
 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;
 }

/**
  * 设置对话框界面
  * @param v View
  * @return
  */
 public Builder setContentView(View v) {
  this.contentView = v;
  return this;
 }

/**
  * Set the positive button resource and it's listener
  *
  * @param confirm_btnText
  * @return
  */
 public Builder setPositiveButton(int confirm_btnText,
   DialogInterface.OnClickListener listener) {
  this.confirm_btnText = (String) context
    .getText(confirm_btnText);
  this.confirm_btnClickListener = listener;
  return this;
 }

/**
  * Set the positive button and it's listener
  *
  * @param confirm_btnText
  * @return
  */
 public Builder setPositiveButton(String confirm_btnText,
   DialogInterface.OnClickListener listener) {
  this.confirm_btnText = confirm_btnText;
  this.confirm_btnClickListener = listener;
  return this;
 }

/**
  * Set the negative button resource and it's listener
  *
  * @param confirm_btnText
  * @return
  */
 public Builder setNegativeButton(int cancel_btnText,
   DialogInterface.OnClickListener listener) {
  this.cancel_btnText = (String) context
    .getText(cancel_btnText);
  this.cancel_btnClickListener = listener;
  return this;
 }

/**
  * Set the negative button and it's listener
  *
  * @param confirm_btnText
  * @return
  */
 public Builder setNegativeButton(String cancel_btnText,
   DialogInterface.OnClickListener listener) {
  this.cancel_btnText = cancel_btnText;
  this.cancel_btnClickListener = 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.mystyle);
  View layout = inflater.inflate(R.layout.customdialog, null);
  dialog.addContentView(layout, new LayoutParams(
    LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
  // set the dialog title
  ((TextView) layout.findViewById(R.id.title)).setText(title);
  ((TextView) layout.findViewById(R.id.title)).getPaint().setFakeBoldText(true);;
  // set the confirm button
  if (confirm_btnText != null) {
   ((Button) layout.findViewById(R.id.confirm_btn))
     .setText(confirm_btnText);
   if (confirm_btnClickListener != null) {
    ((Button) layout.findViewById(R.id.confirm_btn))
      .setOnClickListener(new View.OnClickListener() {
       public void onClick(View v) {
        confirm_btnClickListener.onClick(dialog,
          DialogInterface.BUTTON_POSITIVE);
       }
      });
   }
  } else {
   // if no confirm button just set the visibility to GONE
   layout.findViewById(R.id.confirm_btn).setVisibility(
     View.GONE);
  }
  // set the cancel button
  if (cancel_btnText != null) {
   ((Button) layout.findViewById(R.id.cancel_btn))
     .setText(cancel_btnText);
   if (cancel_btnClickListener != null) {
    ((Button) layout.findViewById(R.id.cancel_btn))
      .setOnClickListener(new View.OnClickListener() {
       public void onClick(View v) {
        cancel_btnClickListener.onClick(dialog,
          DialogInterface.BUTTON_NEGATIVE);

      });
   }

   ((LinearLayout) layout.findViewById(R.id.message))
     .removeAllViews();
   ((LinearLayout) layout.findViewById(R.id.message)).addView(
