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>
