Android 调用系统相机拍照和录制视频，保存照片和视频

1、申请权限

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

java

private static final String[] authBaseArr = {//申请类型
        Manifest.permission.CAMERA,
        Manifest.permission.WRITE_EXTERNAL_STORAGE
};
private static final int authBaseRequestCode = 1;

private boolean hasBasePhoneAuth() {
    PackageManager pm = getPackageManager();
    for (String auth : authBaseArr) {
        if (pm.checkPermission(auth, getPackageName()) != PackageManager.PERMISSION_GRANTED) {
            return false;
        }
    }
    return true;
}

private void initNavi() {
    // 申请权限
    if (android.os.Build.VERSION.SDK_INT >= 23) {
        if (!hasBasePhoneAuth()) {
            this.requestPermissions(authBaseArr, authBaseRequestCode);
            return;
        }
    }
}

2、开始起调相机

private static final int REQUEST_PERMISSION_CODE = 101;
private String SAVE_PIC_PATH = Environment.getExternalStorageState().equalsIgnoreCase(Environment.MEDIA_MOUNTED)
        ? Environment.getExternalStorageDirectory().getAbsolutePath() : "/mnt/sdcard";//

private String SAVE_REAL_PATH = SAVE_PIC_PATH + "/good/savePic";//保存的确
private String ends = "";

                Intent intent = new Intent();
                // 指定开启系统相机的Action
                intent.setAction(MediaStore.ACTION_IMAGE_CAPTURE);//图片
                intent.addCategory(Intent.CATEGORY_DEFAULT);//图片
//                intent.setAction("android.media.action.VIDEO_CAPTURE");//视频
//                intent.addCategory("android.intent.category.DEFAULT");//视频
                // 根据文件地址创建文件
                String subForder = SAVE_REAL_PATH;
                File foder = new File(subForder);
                if (!foder.exists()) foder.mkdirs();

                File file = new File(subForder, System.currentTimeMillis() + ".png");//图片
//                File file = new File(subForder, System.currentTimeMillis() + ".mp4");//视频
                ends = file.getPath();
                if (file.exists()) {
                    file.delete();
                }
                // 把文件地址转换成Uri格式
                Uri uri = Uri.fromFile(file);
                // 设置系统相机拍摄照片完成后图片文件的存放地址
                intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
                startActivityForResult(intent, REQUEST_PERMISSION_CODE);

3、保存图片

调用EXTRA_OUTPUT时，已经保存了图片到文件夹——只是相册不可见

如需相册可见，自定义保存即可

    public void saveBitmapFile(Bitmap bitmap) {
        File file = new File(ends);//将要保存图片的路径
        try {
            BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(file));
            bitmap.compress(Bitmap.CompressFormat.JPEG, 100, bos);
            bos.flush();
            bos.close();
//            FileOutputStream fos = new FileOutputStream(file);
//            bitmap.compress(Bitmap.CompressFormat.PNG, 100, fos);
//            fos.flush();
//            fos.close();
            Intent intent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
            Uri uri = Uri.fromFile(file);
            intent.setData(uri);
            this.sendBroadcast(intent);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
