我是匕首的新手,我的构造函数/方法注入似乎不起作用.不起作用意味着仍然请求注入的字段.
这是我的代码:
@Module
public class AppContextModule {
private final Context appContext;
public AppContextModule(Context appContext) {
this.appContext = appContext;
}
@Singleton
@Provides
public Context getAppContext() {
return appContext;
}
}
@Singleton
@Component(modules = {AppContextModule.class})
public interface MyComponent {
void inject(ActivitiesLifeCycleListener obj);
void inject(WebViewManager obj);
Context context();
}
public final class MyClass {
private final WeakReference<Context> mAppContext;
@Inject
public MyClass(Context context) {
this.mAppContext = context
}
}
public class MyActivity extends BaseActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MyClass …我在我的应用程序中创建了一个方法,将我的布局保存为图像并将其显示在库中.我正试图打开它,但我很难用所有的教程和不同的方法......
这是我的代码:
SimpleDateFormat mTimeFormat = new SimpleDateFormat("dd-MM-yyyy");
Date mTime = new Date();
String mStringTime = mTimeFormat.format(mTime);
String fileFolder = "/orders";
String fileName = "/order-"+mStringTime;
File filePath = new File("/sdcard"+fileFolder+fileName+".png");
Uri fileUri = Uri.fromFile(filePath);
File createFolder = new File(Environment.getExternalStorageDirectory()+fileFolder);
if (!createFolder.exists()){ //checks I don't create the same folder twice
createFolder.mkdir();
}
View orderView = findViewById(R.id.tableOrder); //this is what i shall save
orderView.setDrawingCacheEnabled(true);
Bitmap bitmap = orderView.getDrawingCache();
try {
FileOutputStream outputImage = new FileOutputStream(filePath);
bitmap.compress(CompressFormat.PNG, 10, outputImage);
outputImage.close();
orderView.invalidate();
Intent intentScanner = …
