Android中制作自定义dialog对话框的实例

http://www.jb51.net/article/83319.htm
 
这篇文章主要介绍了Android中制作自定义dialog对话框的实例分享,安卓自带的Dialog显然不够用,因而我们要继承Dialog类来制作自己的对话框,需要的朋友可以参考下
 

自定义dialog基础版
很多时候,我们在使用android sdk提供的alerdialog的时候,会因为你的系统的不同而产生不同的效果,就好比如你刷的是MIUI的系统,弹出框都会在顶部显示!这里简单的介绍自定义弹出框的应用。

首先创建布局文件dialog:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:orientation="vertical" >
  <EditText
    android:id="@+id/edit"
    android:layout_width="250dip"
     android:layout_height="wrap_content"
    />
  <Button
    android:id="@+id/clickbtn"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:text="click me" />
   
 
</LinearLayout>

其次创建MyCustomDialog类继承Dialog:

package com.xzw.custom.dialog;
 
import android.app.Dialog;
import android.content.Context;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
/**
* 自定义dialog
*/
public class MyCustomDialog extends Dialog {
    //定义回调事件,用于dialog的点击事件
    public interface OnCustomDialogListener{
        public void back(String name);
    }
     
    private String name;
    private OnCustomDialogListener customDialogListener;
    EditText etName;
 
    public MyCustomDialog(Context context,String name,OnCustomDialogListener customDialogListener) {
        super(context);
        this.name = name;
        this.customDialogListener = customDialogListener;
    }
     
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.dialog);
        //设置标题
        setTitle(name);
        etName = (EditText)findViewById(R.id.edit);
        Button clickBtn = (Button) findViewById(R.id.clickbtn);
        clickBtn.setOnClickListener(clickListener);
    }
     
    private View.OnClickListener clickListener = new View.OnClickListener() {
         
        @Override
        public void onClick(View v) {
            customDialogListener.back(String.valueOf(etName.getText()));
          MyCustomDialog.this.dismiss();
        }
    };
 
}

最后再完成MainActivity:

package com.xzw.custom.dialog;
 
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;
 
public class MainActivity extends Activity implements OnClickListener {
   private TextView resultText;
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    resultText = (TextView) findViewById(R.id.result);
    Button showDialogBtn = (Button) findViewById(R.id.showdialog);
    showDialogBtn.setOnClickListener(this);
     
    
  }
 
    @Override
    public void onClick(View v) {
         MyCustomDialog dialog = new MyCustomDialog(this,"Enter your name",new MyCustomDialog.OnCustomDialogListener() {
                 
                @Override
                public void back(String name) {
                    resultText.setText("Enter name is "+name);
                     
                }
            });
            dialog.show();
         
  }
          
   
}

效果如图:

炫酷升级版
在日常开发过程中,Android自带的对话框控件美观程度远远满足不了开发的要求,特别是相对于移植开发,下面描述的demo是基于1280X720分辨率实现的效果。

自定义对话框和上次记录的自定义RatingBar非常类似,都是通过在styles.xml里面继承父类(此处是Dialog)的样式。
styles.xml

1
2
3
4
5
6
7
8
<style name="NoticeDialog" parent="@android:style/Theme.Dialog">
    <item name="android:windowFrame">@null</item><!--边框-->
    <item name="android:windowIsFloating">true</item><!--是否浮现在activity之上-->
    <item name="android:windowIsTranslucent">false</item><!--半透明-->
    <item name="android:windowNoTitle">true</item><!--无标题-->
    <item name="android:windowBackground">@drawable/tck_bg</item><!--背景透明-->
    <item name="android:backgroundDimEnabled">false</item><!--模糊-->
  </style>

我们下面将要做下面三个效果:
(1)带选择确认框的提示

2016429151333943.jpg (601×258)

(2)图片+文字的提示

(3)图片+图片

2016429151439752.jpg (613×273)

实现上面三个效果我们只需要继承一个Dialog类,然后根据不同的布局添加相对应的xml布局就可以简单实现功能扩展的效果了。
1.继承Dialog类,重写父类的方法,并添加子类自己的方法。
NoticeDialog.java,继承于Dialog父类,实现了点击事件的接口,如果有确认选择框,则把确认选择框的控件添加click事件监听,通过在回调方法在UI主线程里面实现界面更新和逻辑操作。

package com.zlc.dialog;
  
import android.app.Dialog;
import android.content.Context;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.TextView;
  
  
public class NoticeDialog extends Dialog implements OnClickListener{
  Context context;
  private NoticeDialogListener listener;
  //对话框事件监听接口,用于处理回调点击事件
  public interface NoticeDialogListener {
    public void onClick(View view);
  
  public NoticeDialog(Context context) {
    super(context);
    // TODO Auto-generated constructor stub
    this.context = context;
  }
  public NoticeDialog(Context context,int theme){
    super(context, theme);
    this.context = context;
  }
  public NoticeDialog(Context context,int theme,NoticeDialogListener listener){
    super(context, theme);
    this.context = context;
    this.listener = listener;
  }
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    TextView enter = (TextView)findViewById(R.id.dialog_enter);//确定控件
    TextView cancel = (TextView)findViewById(R.id.dialog_cancle);//取消控件
    if(enter != null && cancel != null){//如果是不带确认选择框,不做事件监听操作
      enter.setOnClickListener(this);
      cancel.setOnClickListener(this);
      enter.requestFocus();
    }
    
  }
  @Override
  public void onClick(View v) {
    // TODO Auto-generated method stub
    listener.onClick(v);
  }
}

2.对应上面三个效果,添加不同的xml布局。
(1)带选择确认框的提示dialog_notice_choise.xml

3.在MainActivity实现对自定义对话框的添加显示。
MainActivity.java,在进行对话框切换显示的时候,只需要设置不同的xml配置文件就行了。(注意:NoticeDialog里面的构造方法的context参数只能是XXXActivity.this,不能是通过getApplicationContext获取的context对象)
