Android 自定义图片选择框

1、效果图：

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);
    }
