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) {

        }
       });
    }
   } else {
    // if no confirm button just set the visibility to GONE
    layout.findViewById(R.id.cancel_btn).setVisibility(

    ((LinearLayout) layout.findViewById(R.id.message))
      .removeAllViews();
    ((LinearLayout) layout.findViewById(R.id.message)).addView(
      contentView, new LayoutParams(

        LayoutParams.WRAP_CONTENT));
   }
   dialog.setContentView(layout);
   return dialog;
