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
