自己封装的dialog控件

自定义dialog肯定是用的很多了 但是感觉每次做都是很乱 单纯完成任务而已,现在封装了一下 以后用到直接copy

 先上图：

主activity

package com.su.testcustomdialog; 
  
import com.su.testcustomdialog.MyDialog.Dialogcallback; 
  
import android.app.Activity; 
import android.os.Bundle; 
import android.view.View; 
import android.widget.Button; 
import android.widget.TextView; 
  
public class CustomDialogActivity extends Activity { 
        private TextView textView; 
  
        /** Called when the activity is first created. */
        @Override
        public void onCreate(Bundle savedInstanceState) { 
                super.onCreate(savedInstanceState); 
                setContentView(R.layout.main); 
                textView = (TextView) findViewById(R.id.textView11); 
                Button button = (Button) findViewById(R.id.button1); 
                button.setOnClickListener(new View.OnClickListener() { 
                        @Override
                        public void onClick(View v) { 
                                MyDialog myDialog = new MyDialog(CustomDialogActivity.this); 
                                myDialog.setContent("哥来自Activity"); 
                                myDialog.setDialogCallback(dialogcallback); 
                                myDialog.show(); 
  
                        } 
                }); 
        } 
/** 
 * 设置mydialog需要处理的事情 
 */
        Dialogcallback dialogcallback = new Dialogcallback() { 
  
                @Override
                public void dialogdo(String string) { 
                        textView.setText("哥來自Dialog: " + string); 
  
                } 
        }; 
  
}

 然后是MyDialog的核心了

 

package com.su.testcustomdialog; 
import android.app.Dialog; 
import android.content.Context; 
import android.view.View; 
import android.widget.Button; 
import android.widget.EditText; 
import android.widget.TextView; 
/** 
 * 自定义dialog 
 * @author sfshine 
 * 
 */
public class MyDialog { 
  
        Context context; 
        Dialogcallback dialogcallback; 
        Dialog dialog; 
        Button sure; 
        TextView textView; 
        EditText editText; 
        /** 
         * init the dialog 
         * @return 
         */
        public MyDialog(Context con) { 
                this.context = con; 
                dialog = new Dialog(context, R.style.dialog); 
                dialog.setContentView(R.layout.dialog); 
                textView = (TextView) dialog.findViewById(R.id.textview); 
                sure = (Button) dialog.findViewById(R.id.button1); 
                editText = (EditText) dialog.findViewById(R.id.editText1); 
  
                sure.setOnClickListener(new View.OnClickListener() { 
  
                        @Override
                        public void onClick(View v) { 
                                dialogcallback.dialogdo(editText.getText().toString()); 
                                dismiss(); 
  
                        } 
                }); 
  
        } 
        /** 
         * 设定一个interfack接口,使mydialog可以處理activity定義的事情 
         * @author sfshine 
         * 
         */
        public interface Dialogcallback { 
                public void dialogdo(String string); 
        } 
  
        public void setDialogCallback(Dialogcallback dialogcallback) { 
                this.dialogcallback = dialogcallback; 
        } 
  
        /** 
         * @category Set The Content of the TextView 
         * */
        public void setContent(String content) { 
                textView.setText(content); 
        } 
  
        /** 
         * Get the Text of the EditText 
         * */
        public String getText() { 
                return editText.getText().toString(); 
        } 
  
        public void show() { 
                dialog.show(); 
        } 
  
        public void hide() { 
                dialog.hide(); 
        } 
  
        public void dismiss() { 
                dialog.dismiss(); 
        } 
  
}

dialog的布局

<?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="wrap_content"
    android:layout_margin="30.0dp"
    android:orientation="vertical"
    android:padding="10dip" > 
  
    <!-- 这里如果使用android:layout_width="5000dip"设置一个极大的值 系统就会 -->
  
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="30.0dp"
        android:gravity="center"
        android:text="自定义Dialog"
        android:textColor="#F0F"
        android:textSize="20dip" /> 
  
    <TextView
        android:id="@+id/textview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" /> 
  
    <EditText
        android:id="@+id/editText1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:ems="10" > 
    </EditText> 
  
    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="right"
        android:text="確定" /> 
  
</LinearLayout>

style 的文件

<?xml version="1.0" encoding="utf-8"?> 
<resources> 
  
    <style name="dialog" parent="@android:style/Theme.Dialog"> 
        <item name="android:windowFrame">@null</item> 
        <item name="android:windowIsFloating">true</item> 
        <item name="android:windowIsTranslucent">false</item> 
        <item name="android:windowNoTitle">true</item> 
        <item name="android:background">#FFF</item> 
        <item name="android:windowBackground">@android:color/transparent</item> 
        <item name="android:backgroundDimEnabled">true</item> 
    </style> 
  
</resources>
