自定义Dialog

1、layout - dialog_layout.xml

<?xml version="1.0" encoding="UTF-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:id="@+id/dialoglayout"    android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:background="@color/dialog_bg"    android:fadingEdge="horizontal"    android:orientation="vertical" >    <TextView        android:id="@+id/title"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:gravity="center_vertical"        android:paddingBottom="12.0dip"        android:paddingLeft="16.0dip"        android:paddingRight="16.0dip"        android:paddingTop="12.0dip"        android:text="阿萨德"        android:textColor="@color/dialog_title"        android:textSize="18.0sp" />    <ImageView        android:id="@+id/dialog_title_border"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:background="@drawable/line_separate_blue" />    <LinearLayout        android:id="@+id/content"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:layout_weight="1.0"        android:gravity="center" >        <TextView            android:id="@+id/message"            android:layout_width="fill_parent"            android:layout_height="wrap_content"            android:layout_marginBottom="10.0dip"            android:layout_marginTop="10.0dip"            android:paddingLeft="30.0dip"            android:paddingRight="10.0dip"            android:text="阿萨德"            android:textColor="@android:color/black"            android:textSize="20.0dip"            android:visibility="visible" />    </LinearLayout>    <LinearLayout        android:id="@+id/mydialogbuttonlayout"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:background="@color/dialog_btn_group_bg"        android:paddingRight="4.0dip" >        <Button            android:id="@+id/positiveButton"            style="@style/DialogBottomBtn"            android:layout_width="fill_parent"            android:layout_height="fill_parent"            android:layout_marginBottom="4.0dip"            android:layout_marginLeft="4.0dip"            android:layout_marginTop="4.0dip"            android:layout_weight="1.0"            android:text="阿萨德" />        <Button            android:id="@+id/neutralButton"            style="@style/DialogBottomBtn"            android:layout_width="fill_parent"            android:layout_height="fill_parent"            android:layout_marginBottom="4.0dip"            android:layout_marginLeft="4.0dip"            android:layout_marginTop="4.0dip"            android:layout_weight="1.0"            android:text="阿萨德" />        <Button            android:id="@+id/negativeButton"            style="@style/DialogBottomBtn"            android:layout_width="fill_parent"            android:layout_height="fill_parent"            android:layout_marginBottom="4.0dip"            android:layout_marginLeft="4.0dip"            android:layout_marginTop="4.0dip"            android:layout_weight="1.0"            android:text="阿萨德" />    </LinearLayout></LinearLayout>

2、styles.xml

<?xml version="1.0" encoding="UTF-8"?><resources>    <style name="Dialog" parent="android:style/Theme.Dialog">        <item name="android:windowNoTitle">true</item>        <item name="android:windowFrame">@null</item>        <item name="android:windowIsFloating">true</item>        <item name="android:windowIsTranslucent">false</item>    </style>    <style name="DialogText">        <item name="android:textColor">#FF000000</item>        <item name="android:textSize">12sp</item>    </style>    <style name="DialogText.Title">        <item name="android:textSize">20sp</item>        <item name="android:textColor">#FFFFFF</item>        <item name="android:textStyle">bold</item>    </style>    <style name="DialogBottomBtn">        <item name="android:textSize">18.0sp</item>        <item name="android:textColor">@android:color/black</item>        <item name="android:background">@drawable/window_btn_bg_selector</item>        <item name="android:paddingLeft">16.0dip</item>        <item name="android:paddingTop">12.0dip</item>        <item name="android:paddingRight">16.0dip</item>        <item name="android:paddingBottom">12.0dip</item>        <item name="android:minWidth">80.0dip</item>    </style></resources>

3、代码

               for (int i = 0; i < items.length; i++)                {                    final int pos = i;                    TextView text = new TextView(context);                    text.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, 80));

                               Mydialog.dismiss();                            }                        });                    }                }            }            else if (contentView != null)            {                ((LinearLayout)layout.findViewById(R.id.content)).removeAllViews();                ((LinearLayout)layout.findViewById(R.id.content)).setPadding(left, top, right, bottom);                ((LinearLayout)layout.findViewById(R.id.content)).addView(contentView, new LayoutParams(                    LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));            }            Mydialog.setContentView(layout);            return Mydialog;        }    }}

4、应用

clickme.setOnClickListener(new OnClickListener(){     @Override     public void onClick(View v)     {MyDialog.Builder myDialog = new MyDialog.Builder(MainA.this);myDialog.setTitle("Farmer");myDialog.setMessage("小强好帅！");// 可以复用中间的content页面//LayoutInflater inflater = (LayoutInflater)getSystemService(Service.LAYOUT_INFLATER_SERVICE);//View view = inflater.inflate(R.layout.third, null);//myDialog.setView(view);myDialog.setPositiveButton("OK", new DialogInterface.OnClickListener(){@Overridepublic void onClick(DialogInterface dialog, int which){}});myDialog.setNeutralButton("hha", new DialogInterface.OnClickListener(){@Overridepublic void onClick(DialogInterface dialog, int which){}});myDialog.setNegativeButton("Cancel", new DialogInterface.OnClickListener(){@Overridepublic void onClick(DialogInterface dialog, int which){}});myDialog.create().show();     }});

5、截图显示

        

6、有些机型，把Dialog改掉了，使用自定义的会有很难看的边框，可以改一下Dialog的样式，如下：

<style name="Dialog" parent="android:style/Theme.Dialog"><item name="android:windowNoTitle">true</item><item name="android:windowFrame">@null</item>  <item name="android:windowIsFloating">true</item>  <item name="android:windowIsTranslucent">false</item>  <item name="android:background">@android:color/black</item>  <item name="android:windowBackground">@null</item></style>
