ImageFileSelector

轻量级的选取图片和裁切图片的库，使用系统自带的软件实现。

#####支持Android版本：Android 2.2+

使用方法

Maven

<dependency>
  <groupId>com.sw926.imagefileselector</groupId>
  <artifactId>library</artifactId>
  <version>1.0.1</version>
  <type>aar</type>
</dependency>

Gradle

compile 'com.sw926.imagefileselector:library:1.0.1'

选取图片

初始化

ImageFileSelector mImageFileSelector = new ImageFileSelector(this);
mImageFileSelector.setCallback(new ImageFileSelector.Callback() {
    @Override
    public void onSuccess(final String file) {
        // 选取图片成功
    }

    @Override
    public void onError() {
        // 选取图片失败
    }
});

在Activity中，加入以下代码

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    mImageFileSelector.onActivityResult(requestCode, resultCode, data);
}

@Override
protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    mImageFileSelector.onSaveInstanceState(outState);
}

@Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
    super.onRestoreInstanceState(savedInstanceState);
    mImageFileSelector.onRestoreInstanceState(savedInstanceState);
}

// Android 6.0的动态权限
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    mImageFileSelector.onRequestPermissionsResult(requestCode, permissions, grantResults);
}

设置参数

// 设置输出文件的尺寸
mImageFileSelector.setOutPutImageSize(800, 600);
// 设置保存图片的质量 0到100
mImageFileSelector.setQuality(80)；

现在开始选取图片

// 拍照选取
mImageFileSelector.takePhoto(this);
// 从文件选取
mImageFileSelector.selectImage(this);

所有选取的图片都在

/sdcard/Android/data/{packagename}/cache/image/image_selector

使用完记得删除

裁切图片

初始化

ImageCropper mImageCropper = new ImageCropper(this);
mImageCropper.setCallback(new ImageCropper.ImageCropperCallback() {
    @Override
    public void onCropperCallback(ImageCropper.CropperResult result, File srcFile, File outFile) {
        if (result == ImageCropper.CropperResult.success) {
            // 成功
        } else if (result == ImageCropper.CropperResult.error_illegal_input_file) {
            // 输入的文件失败
        } else if (result == ImageCropper.CropperResult.error_illegal_out_file) {
            // 输出文件失败
        }
    }
});

在Activit中加入以下代码

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    mImageCropper.onActivityResult(requestCode, resultCode, data);
}

@Override
protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    mImageCropper.onSaveInstanceState(outState);
}

@Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
    super.onRestoreInstanceState(savedInstanceState);
    mImageCropper.onRestoreInstanceState(savedInstanceState);
}

设置参数

// 设置输出文件的宽高比
mImageCropper.setOutPutAspect(1, 1);
// 设置输出文件的尺寸
mImageCropper.setOutPut(800, 800);
// 设置是否缩放到指定的尺寸
mImageCropper.setScale(true);

裁切图片

mImageCropper.cropImage(file);
