拍照

一,执行拍照

/*
* 开始拍照
* */
public void takePhoto() {
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    //照片保存目录
   file = new File(Environment.getExternalStorageDirectory(), STORAGE_PICTURE_NAME + System.currentTimeMillis() + ".jpg");
    if (Build.VERSION.SDK_INT >= 24) {
        fileUri = FileProvider.getUriForFile(this, this.getPackageName() + ".provider", file);
    } else {
        fileUri = Uri.fromFile(file);
    }
    intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
    startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);

}

二,拍照返回

case CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE: //拍照返回

  File destFile = new File(Environment.getExternalStorageDirectory().getPath(), COMPRESS_PICTURE_NAME + System.currentTimeMillis() + ".jpg");
    File compressFile = BitmapUtil.compressPicture(this.file.getAbsolutePath(), destFile.getAbsolutePath(), 500, 500);
    FileUtils.deleteFileByName(Environment.getExternalStorageDirectory().getPath(), STORAGE_PICTURE_NAME);
    //TODO
    MLog.e("date", "压缩路径:" + destFile.getAbsolutePath());
    Bitmap bitmap = BitmapFactory.decodeFile(compressFile.getAbsolutePath());
    mImageLists.add(compressFile.getAbsolutePath());

    break;

三,配置FileProvider

FileProvider作用:Android7.0后,通过它在应用建共享文件

<provider
    android:name="android.support.v4.content.FileProvider"
    android:authorities="com.mbox.cn.provider"
    android:exported="false"
    android:grantUriPermissions="true">
    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/filepaths"/>
</provider>

在res下新建xml文件夹,新建filepaths文件

<?xml version="1.0" encoding="utf-8"?>
<paths>
    <root-path path="." name="external_storage_root" />
</paths>
