Android中使用相机和相册获取照片，模仿朋友圈发说说

话不多说，直接上图，如图：

这个功能相信很多人都会用到，下面来一步一步的设置这个功能。

1：首先布局我们的主界面，这里我使用activity_edit_diary.xml文件来当布局文件；

文件内容如下：

<?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:background="@color/white"android:orientation="vertical"><!--写日记头部标题栏--><RelativeLayoutandroid:layout_width="match_parent"android:layout_height="@dimen/title_bar_height"android:background="@drawable/bg_color_white"><TextViewandroid:layout_width="match_parent"android:layout_height="match_parent"android:gravity="center"android:text="写日记"android:textColor="@color/titleBlack"android:textSize="@dimen/title_bar_title_size" /><ImageViewandroid:id="@+id/edit_diary_back"android:layout_width="wrap_content"android:layout_height="@dimen/title_bar_height"android:layout_alignParentStart="true"android:layout_centerInParent="true"android:contentDescription="@string/word_back"android:onClick="onClick"android:paddingStart="16dp"android:src="@drawable/nav_icon_return_black" /><TextViewandroid:id="@+id/send_diary"android:layout_width="wrap_content"android:layout_height="@dimen/title_bar_height"android:layout_alignParentEnd="true"android:layout_centerInParent="true"android:contentDescription="发送"android:gravity="center"android:paddingEnd="16dp"android:text="发送"android:textColor="@color/textColor"android:textSize="15sp" /></RelativeLayout><!--头标题下的下划线--><TextViewandroid:layout_width="match_parent"android:layout_height="1dp"android:background="@color/loginLine" /><!--写日记，上传照片等输入框--><LinearLayoutandroid:layout_width="match_parent"android:layout_height="wrap_content"android:layout_margin="16dp"android:orientation="vertical"><EditTextandroid:id="@+id/edit_diary_text"android:layout_width="match_parent"android:layout_height="80dp"android:background="@color/white"android:gravity="top"android:hint="说点什么吧..."android:maxLines="5"android:textSize="13sp" /><!--GridView高度是自适应--><GridViewandroid:id="@+id/picture_gridView"android:layout_width="match_parent"android:layout_height="wrap_content"android:numColumns="3" /><!--可见范围--><LinearLayoutandroid:id="@+id/public_secret_layout"android:layout_width="match_parent"android:layout_height="30dp"android:layout_marginTop="10dp"android:background="@color/white"android:gravity="center"android:orientation="horizontal"><TextViewandroid:layout_width="0dp"android:layout_height="wrap_content"android:layout_weight="1" /><TextViewandroid:layout_width="wrap_content"android:layout_height="wrap_content"android:text="可见范围：" /><TextViewandroid:id="@+id/public_secret_text"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="公开" /><ImageViewandroid:id="@+id/public_secret"android:layout_width="22dp"android:layout_height="22dp"android:src="@drawable/icon_arrow1" /></LinearLayout></LinearLayout>
</LinearLayout>

2：布局我们的弹框，我设置的弹框名为pop_edit_diary.xml文件，如下：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"android:layout_width="match_parent"android:layout_height="match_parent"android:background="#99444444"android:fitsSystemWindows="true"android:gravity="center|bottom"android:orientation="vertical"><android.support.v7.widget.CardViewandroid:layout_width="wrap_content"android:layout_height="wrap_content"app:cardCornerRadius="13dp"app:cardElevation="0dp"><LinearLayoutandroid:layout_width="340dp"android:layout_height="wrap_content"android:background="@color/white"android:gravity="center"android:orientation="vertical"><!--如果不加这层布局那么就会报错--><LinearLayoutandroid:id="@+id/public_layout"android:layout_width="match_parent"android:layout_height="wrap_content"android:orientation="vertical"><TextViewandroid:id="@+id/public_text"android:layout_width="match_parent"android:layout_height="57dp"android:gravity="center"android:text="公开"android:textColor="@color/takePhoto"android:textSize="20sp" /><Viewandroid:layout_width="match_parent"android:layout_height="1dp"android:background="@color/viewGrays" /></LinearLayout><LinearLayoutandroid:id="@+id/secret_layout"android:layout_width="match_parent"android:layout_height="wrap_content"><TextViewandroid:id="@+id/secret_text"android:layout_width="match_parent"android:layout_height="57dp"android:gravity="center"android:text="秘密"android:textColor="@color/takePhoto"android:textSize="20sp" /></LinearLayout></LinearLayout></android.support.v7.widget.CardView><android.support.v7.widget.CardViewandroid:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_marginBottom="10dp"android:layout_marginTop="10dp"app:cardCornerRadius="13dp"app:cardElevation="0dp"><LinearLayoutandroid:id="@+id/cancel_public_secret_layout"android:layout_width="match_parent"android:layout_height="wrap_content"><TextViewandroid:id="@+id/cancel_public_secret"android:layout_width="340dp"android:layout_height="57dp"android:gravity="center"android:text="取消"android:textColor="@color/takePhoto"android:textSize="20sp" /></LinearLayout></android.support.v7.widget.CardView>
</LinearLayout>

3:基本的布局都设置好了之后下面就是我们的重点界面了：主界面是EditDiaryActivity.java,

文件中的代码如下：

//            return;
//        }switch (requestCode) {case TAKE_PHOTO:if (resultCode == RESULT_OK) {final Uri uri = imageUri;String path = ImageTool.getImageAbsolutePath(this, uri);if (list.size() == IMG_COUNT) {removeItem();refreshAdapter();return;}removeItem();list.add(path);list.add(IMG_ADD_TAG);refreshAdapter();//这里先弹出一个吐司Toast.makeText(this, "调用摄像头结束", Toast.LENGTH_SHORT).show();}break;//调用相册获取照片case TAKE_ALBUM:if (resultCode == RESULT_OK) {final Uri uri = data.getData();String path = ImageTool.getImageAbsolutePath(this, uri);System.out.println(path);if (list.size() == IMG_COUNT) {removeItem();refreshAdapter();return;}removeItem();list.add(path);list.add(IMG_ADD_TAG);refreshAdapter();}break;default:break;}//数据回调后关闭弹窗popupWindow.dismiss();}private void removeItem() {if (list.size() != IMG_COUNT) {if (list.size() != 0) {list.remove(list.size() - 1);}}}/*** 从这里开始加载可见范围弹框的*/private void initPopUp() {initAd();showPopUp();}/*** --------------弹窗显示-----------------*/private void showPopUp() {if (popupWindow.isShowing()) {popupWindow.dismiss();}popupWindow.showAtLocation(popUp, Gravity.BOTTOM, 0, 0);}//初始化弹框private void initAd() {popUp = getLayoutInflater().inflate(R.layout.pop_edit_diary, null);popupWindow = new PopupWindow(popUp, ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT, true);popupWindow.setTouchInterceptor(new View.OnTouchListener() {@Overridepublic boolean onTouch(View view, MotionEvent motionEvent) {return false;}});initEvents();}private void initEvents() {popUp.findViewById(R.id.cancel_public_secret_layout).setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {popupWindow.dismiss();}});//调用摄像头拍照popUp.findViewById(R.id.public_layout).setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {publicSecretText.setText("公开");popupWindow.dismiss();}});popUp.findViewById(R.id.secret_layout).setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {publicSecretText.setText("秘密");popupWindow.dismiss();}});}/*** 从这里开始加载照片选择弹框的*/private void initImagePopUp() {initImageAd();showImagePopUp();}/*** --------------照片选择弹窗显示-----------------*/private void showImagePopUp() {if (popupWindow.isShowing()) {popupWindow.dismiss();}popupWindow.showAtLocation(popUp, Gravity.BOTTOM, 0, 0);}//初始化选择照片弹框private void initImageAd() {popUp = getLayoutInflater().inflate(R.layout.pop_user_info, null);popupWindow = new PopupWindow(popUp, ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT, true);popupWindow.setTouchInterceptor(new View.OnTouchListener() {@Overridepublic boolean onTouch(View view, MotionEvent motionEvent) {return false;}});initImageEvents();}private void initImageEvents() {popUp.findViewById(R.id.cancel_take_photo_layout).setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {popupWindow.dismiss();}});//调用摄像头拍照popUp.findViewById(R.id.take_photo_layout).setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {//调用相机File outputImage = new File(getExternalCacheDir(), "output_image.jpg");try {if (outputImage.exists()) {outputImage.delete();}outputImage.createNewFile();} catch (IOException e) {e.printStackTrace();}if (Build.VERSION.SDK_INT >= 24) {imageUri = FileProvider.getUriForFile(EditDiaryActivity.this,"com.choicelean.superwinner.fileprovider", outputImage);} else {imageUri = Uri.fromFile(outputImage);}Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);startActivityForResult(intent, TAKE_PHOTO);popupWindow.dismiss();}});//调用相册选取照片popUp.findViewById(R.id.camera_layout).setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);startActivityForResult(i, TAKE_ALBUM);popupWindow.dismiss();}});}}

4:这里使用到了GridView，自然想到设置一个子项布局用来存放每一张图片子项布局名为activity_edit_diary_select_photo：

代码如下所示：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="110dp"android:layout_height="110dp"android:layout_gravity="center"android:gravity="center"><com.choicelean.superwinner.component.SquareRelativeLayoutxmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="110dp"android:layout_height="110dp"><FrameLayoutandroid:layout_width="90dp"android:layout_height="90dp"android:layout_centerInParent="true"android:background="#FFF5F5F5"><ImageViewandroid:id="@+id/null_view"android:layout_width="22dp"android:layout_height="22dp"android:src="@drawable/icon_add"android:layout_gravity="center"/><ImageViewandroid:id="@+id/main_gridView_item_photo"android:layout_width="90dp"android:layout_height="90dp"android:layout_centerInParent="true"android:layout_gravity="center"android:scaleType="fitXY" /></FrameLayout><CheckBoxandroid:id="@+id/main_gridView_item_cb"android:layout_width="20dp"android:layout_height="20dp"android:layout_alignParentEnd="true"android:layout_alignParentTop="true"android:background="@drawable/growup_close"android:gravity="center" /></com.choicelean.superwinner.component.SquareRelativeLayout>
</LinearLayout>

5：这里获取拍照的照片的时候使用到内容提供者：所以在我们的清单文件中添加如下代码：

<!-- 这个内容提供者是在上面的EditDiaryActivity中的 -->
<providerandroid:name="android.support.v4.content.FileProvider"android:authorities="com.choicelean.superwinner.fileprovider"android:exported="false"android:grantUriPermissions="true"><meta-dataandroid:name="android.support.FILE_PROVIDER_PATHS"android:resource="@xml/file_paths" />
</provider>

6:使用内容提供者就想到了图片的存放路径，故在我们的res文件下新建一个包取名为xml,在包下新建file_paths.xml文件：

代码如下：

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android"><!--下面的这个path路径不写就是默认SD卡的路径，也可以只写我们放图片的路径上--><external-path name="my_images" path=""/>
</paths>

7：最后一步在我们的清单文件中别忘了声明权限：

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

8：补充一个工具类

}
