android 调用相机拍照及相册

调用系统相机拍照：

private Button btnDyxj;
private ImageView img1;
private File tempFile;
btnDyxj = (Button) findViewById(R.id.btnXj);
img1 = (ImageView) findViewById(R.id.img1);

private void camera() {
    // 判断存储卡是否可以用，可用进行存储
    if (hasSdcard()) {

        File dir = new File(IMAGE_DIR);
        if (!dir.exists()) {
            dir.mkdir();
        }
        tempFile = new File(dir,
                System.currentTimeMillis() + "_" + PHOTO_FILE_NAME);
        //从文件中创建uri
        Uri uri = Uri.fromFile(tempFile);
        Intent intent = new Intent();
        intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
        intent.setAction(MediaStore.ACTION_IMAGE_CAPTURE);
        intent.addCategory(intent.CATEGORY_DEFAULT);
        // 开启一个带有返回值的Activity，请求码为PHOTO_REQUEST_CAREMA
        startActivityForResult(intent, 1);
    } else {
        Toast.makeText(this, "未找到存储卡，无法拍照！", Toast.LENGTH_SHORT).show();
    }
}
/**
 * 判断sdcard是否被挂载
 */
private boolean hasSdcard() {
    return Environment.getExternalStorageState().equals(
            Environment.MEDIA_MOUNTED);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK) {
        if (requestCode == 1) {
            if (resultCode != RESULT_CANCELED) {
                // 从相机返回的数据
                if (hasSdcard()) {
                    if (tempFile != null) {
                        uploadImage(tempFile.getPath());
                    } else {
                        Toast.makeText(this, "相机异常请稍后再试！", Toast.LENGTH_SHORT).show();
                    }

                    Log.i("images", "拿到照片path=" + tempFile.getPath());
                } else {
                    Toast.makeText(this, "未找到存储卡，无法存储照片！", Toast.LENGTH_SHORT).show();
                }
            }
        }

    }
}

/**
 * 上传图片
 *
 * @param path
 */
private void uploadImage(final String path) {
    new Thread() {
        @Override
        public void run() {
            if (new File(path).exists()) {
                Log.d("images", "源文件存在" + path);
            } else {
                Log.d("images", "源文件不存在" + path);
            }

            File dir = new File(IMAGE_DIR);
            if (!dir.exists()) {
                dir.mkdir();
            }
            final File file = new File(dir + "/temp_photo" + System.currentTimeMillis() + ".jpg");
            NativeUtil.compressBitmap(path, file.getAbsolutePath(), 50);
            if (file.exists()) {
                Log.d("images", "压缩后的文件存在" + file.getAbsolutePath());
            } else {
                Log.d("images", "压缩后的不存在" + file.getAbsolutePath());
            }
            Message message = new Message();
            message.what = 0xAAAAAAAA;
            message.obj = file.getAbsolutePath();
            handler.sendMessage(message);

        }
    }.start();

}

Handler handler = new Handler() {
    @Override
    public void handleMessage(Message msg) {
        super.handleMessage(msg);
        if (msg.what == 0xAAAAAAAA) {
            photoPath(msg.obj.toString());
        }

    }
};

public void photoPath(String path) {
    Glide.with(this)
            .load(path)
            .priority(Priority.HIGH)
            .into(img1);
}

调用系统化相册：

    /**
     * 从相册获取2
     */
    public void gallery() {
        Intent intent = new Intent(
                Intent.ACTION_PICK,
                MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
        startActivityForResult(intent, 2);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode == RESULT_OK) {
            if (requestCode == 2) {
                // 从相册返回的数据
                if (data != null) {
                    // 得到图片的全路径
                    Uri uri = data.getData();
                    String[] proj = {MediaStore.Images.Media.DATA};
                    //好像是android多媒体数据库的封装接口，具体的看Android文档
                    Cursor cursor = managedQuery(uri, proj, null, null, null);
                    //按我个人理解 这个是获得用户选择的图片的索引值
                    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
                    //将光标移至开头 ，这个很重要，不小心很容易引起越界
                    cursor.moveToFirst();
                    //最后根据索引值获取图片路径
                    String path = cursor.getString(column_index);

                    uploadImage(path);
                }
            }
        }
    }

    /**
     * 上传图片

     */
    private void uploadImage(final String path) {
        new Thread() {
            @Override
            public void run() {
                if (new File(path).exists()) {
                    Log.d("images", "源文件存在" + path);
                } else {
                    Log.d("images", "源文件不存在" + path);
                }

                File dir = new File(IMAGE_DIR);
                if (!dir.exists()) {
                    dir.mkdir();
                }
                final File file = new File(dir + "/temp_photo" + System.currentTimeMillis() + ".jpg");
                NativeUtil.compressBitmap(path, file.getAbsolutePath(), 50);
                if (file.exists()) {
                    Log.d("images", "压缩后的文件存在" + file.getAbsolutePath());
                } else {
                    Log.d("images", "压缩后的不存在" + file.getAbsolutePath());
                }
                Message message = new Message();
                message.what = 0xAAAAAAAA;
                message.obj = file.getAbsolutePath();
                handler.sendMessage(message);

            }
        }.start();
    }

    Handler handler = new Handler() {
        @Override
        public void handleMessage(Message msg) {
            super.handleMessage(msg);
            if (msg.what == 0xAAAAAAAA) {
                photoPath(msg.obj.toString());
            }
        }
    };

    public void photoPath(String path) {
        Map<String, Object> map = new HashMap<>();
        map.put("path", path);
        Glide.with(this)
                .load(path)
                .priority(Priority.HIGH)
                .into(img1);
    }
