1、效果图：
这里写图片描述
2、布局文件：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="320dp"    android:layout_height="wrap_content"    android:background="@color/bg_gray"    android:orientation="vertical" >    <TextView        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_marginLeft="15dp"        android:layout_marginRight="15dp"        android:layout_marginTop="10dp"        android:gravity="center"        android:text="获取图片"        android:textSize="14sp" />    <Button        android:id="@+id/dialog_btn_gallery"        android:layout_width="match_parent"        android:layout_height="45dp"        android:layout_marginLeft="15dp"        android:layout_marginRight="15dp"        android:layout_marginTop="10dp"        android:background="@drawable/btn_green_selector"        android:text="从相册获取"        android:textColor="@color/white"        android:textSize="20sp" />    <Button        android:id="@+id/dialog_btn_camera"        android:layout_width="match_parent"        android:layout_height="45dp"        android:layout_marginLeft="15dp"        android:layout_marginRight="15dp"        android:layout_marginTop="20dp"        android:background="@drawable/btn_green_selector"        android:text="拍摄照片获取"        android:textColor="@color/white"        android:textSize="20sp" />    <Button        android:id="@+id/dialog_btn_cancel"        android:layout_width="match_parent"        android:layout_height="45dp"        android:layout_marginBottom="35dp"        android:layout_marginLeft="15dp"        android:layout_marginRight="15dp"        android:layout_marginTop="20dp"        android:background="@drawable/btn_gray_selector"        android:text="取消"        android:textColor="@color/white"        android:textSize="20sp" /></LinearLayout>

3、按钮样式选择器:

<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android">    <item android:drawable="@drawable/g_green_btn_pressed" android:state_pressed="true"/>    <item android:drawable="@drawable/g_green_btn_disbabled" android:state_enabled="false"/>    <item android:drawable="@drawable/g_green_btn_normal"/></selector>

4、自定义对话框样式文件

<style name="dialog_logout" 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">@color/transparent</item> <!-- 背景透明 -->        <item name="android:backgroundDimEnabled">true</item> <!-- 模糊 -->        <item name="android:windowAnimationStyle">@android:style/Animation.InputMethod</item>    </style>

5、对话框代码：

/** * @描述         选择图片对话框 * @项目名称      App_Chat * @包名         com.android.chat.views * @类名         DialogChooseImage * @author      chenlin * @date        2014年6月25日 下午9:44:22 * @version     1.0 */public class DialogChooseImage extends Dialog {    public DialogChooseImage(Context context) {        super(context, R.style.dialog_logout);        setCanceledOnTouchOutside(true);    }    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        LayoutParams params = getWindow().getAttributes();        params.gravity = Gravity.BOTTOM;        setContentView(R.layout.dialog_choose_image);        findViewById(R.id.dialog_btn_cancel).setOnClickListener(                new View.OnClickListener() {                    @Override                    public void onClick(View v) {                        dismiss();                    }                });    }    public void setClickCameraListener(View.OnClickListener listener) {        findViewById(R.id.dialog_btn_camera).setOnClickListener(listener);    }    public void setClickGalleryListener(View.OnClickListener listener) {        findViewById(R.id.dialog_btn_gallery).setOnClickListener(listener);    }}

6、使用方法：

private void openChooseDialog() {        final DialogChooseImage dialog = new DialogChooseImage(getActivity());        dialog.show();        dialog.setClickCameraListener(new OnClickListener() {            @Override            public void onClick(View v) {                getImageFromCamera();                dialog.dismiss();            }        });        dialog.setClickGalleryListener(new OnClickListener() {            @Override            public void onClick(View v) {                getimageFromGallery();                dialog.dismiss();            }        });    }protected void getimageFromGallery() {        Intent intent = new Intent("android.intent.action.PICK");        intent.setDataAndType(MediaStore.Images.Media.INTERNAL_CONTENT_URI, "image/*");        intent.putExtra("output", Uri.fromFile(sdcardTempFile));        intent.putExtra("crop", "true");        intent.putExtra("aspectX", 1);// 裁剪框 intent.putExtra("aspectY", 1);        intent.putExtra("outputX", crop);// 输出图片大小        intent.putExtra("outputY", crop);        startActivityForResult(intent, REQUEST_CODE_GALLERY);    }    protected void getImageFromCamera() {        Uri uri = Uri.fromFile(sdcardTempFile);        Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");        intent.putExtra("output", uri);        startActivityForResult(intent, REQUEST_CODE_CAMERA);    }
