我尝试使用HiAI创建一个应用程序来尝试图像超分辨率。
活动代码如下所示：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_isr);
Thread thread = new Thread(
new Runnable() {
@Override
public void run() {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"),
1001);
}
}
);
thread.start();
try {
thread.join();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1001 && resultCode == RESULT_OK) {
// Let's read picked image data - its URI
Uri pickedImage = data.getData();
// Let's read picked image path using content resolver
String[] filePath = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(pickedImage, filePath, null, null, null);
cursor.moveToFirst();
String imagePath = cursor.getString(cursor.getColumnIndex(filePath[0]));
BitmapFactory.Options options = new BitmapFactory.Options();
options.inPreferredConfig = Bitmap.Config.ARGB_8888;
bitmap = BitmapFactory.decodeFile(imagePath, options);
// Do something with the bitmap
bitmap = ShrinkBitmap(imagePath, 700, 500);
ImageView img = findViewById(R.id.imageView);
img.setImageBitmap(bitmap);
// At the end remember to close the cursor or you will end with the RuntimeException!
cursor.close();
}
}
public void press(View v) {
Log.i("AI", "Feladat előtt");
VisionBase.init(this, new ConnectionCallback() {
@Override
public void onServiceConnect() {
}
@Override
public void onServiceDisconnect() {
}
});
/** Define class detector，the context of this project is the input parameter */
ImageSuperResolution superResolution = new ImageSuperResolution(this);
/** Define the frame, put the bitmap that needs to detect the image into the frame*/
Frame frame = new Frame();
/** BitmapFactory.decodeFile input resource file path*/
//Bitmap bitmap = BitmapFactory.decodeFile(null); //TODO
frame.setBitmap(bitmap);
/** Define and set super-resolution parameters*/
SuperResolutionConfiguration paras = new SuperResolutionConfiguration(
SuperResolutionConfiguration.SISR_SCALE_3X,
SuperResolutionConfiguration.SISR_QUALITY_HIGH);
superResolution.setSuperResolutionConfiguration(paras);
/** Run super-resolution and get result of processing */
ImageResult result = superResolution.doSuperResolution(frame, null);
/** After the results are processed to get bitmap*/
Bitmap bmp = result.getBitmap();
/** Note: The result and the Bitmap in the result must be NULL, but also to determine whether the returned error code is 0 (0 means no error)*/
/** Source release */
VisionBase.destroy();
Log.i("AI", "Destroy után");
v.setVisibility(View.GONE);
ImageView img = findViewById(R.id.imageView);
img.setImageBitmap(bmp);
Log.i("AI", "Kirajzolva");
}
Bitmap ShrinkBitmap(String file, int width, int height) {
BitmapFactory.Options bmpFactoryOptions = new BitmapFactory.Options();
bmpFactoryOptions.inJustDecodeBounds = true;
Bitmap bitmap;
BitmapFactory.decodeFile(file, bmpFactoryOptions);
int heightRatio = (int) Math.ceil(bmpFactoryOptions.outHeight / (float) height);
int widthRatio = (int) Math.ceil(bmpFactoryOptions.outWidth / (float) width);
if (heightRatio > 1 || widthRatio > 1) {
if (heightRatio > widthRatio) {
bmpFactoryOptions.inSampleSize = heightRatio;
} else {
bmpFactoryOptions.inSampleSize = widthRatio;
}
}
bmpFactoryOptions.inJustDecodeBounds = false;
bmpFactoryOptions.inPreferredConfig = Bitmap.Config.ARGB_8888;
bitmap = BitmapFactory.decodeFile(file, bmpFactoryOptions);
return bitmap;
}
它启动图库应用程序，选择图片，将图片裁剪为良好的分辨率，并启动一个按钮来启动AI功能以工作。它应该在图像视图中显示图片。 但是，当我在手机上运行该应用程序时，在我按下按钮让AI做它的事情后，出现了以下4个错误：
java.lang.IllegalStateException: Could not execute method for android:onClick

app/libs 文件夹中有 3 个文件：
- vision-oversea-release.aar - 这是由DevEco自动添加 的
- huawei-hiai-vision.aar - 这是华为网站的zip文件
- Huawei_IDE.jar - 这是在网站的另一个zip中，并作为最后一次测试添加，但它没有解决任何问题。
build.gradle 看起来像这样：
apply plugin: 'com.android.application'
android {
compileSdkVersion 27
defaultConfig {
multiDexEnabled true
applicationId "hu.hiai.aitestapp"
minSdkVersion 26

如果有人能帮忙，我将不胜感激！
我的同事也有类似的问题，当他的代码调用 FaceCompare 方法时就会发生这种情况。碰巧的是，HiAI库中没有这样的类。那我们该怎么办呢？
如果在 UI 线程中调用 FaceCompare 方法，它看起来像是抛出的，因此我们将其移动到另一个线程，我们不再遇到该异常。
