Download: Msecurityinputmethodservice is null

This effectively lets you determine if the application window is entirely covered when this returns true or if some part of it may be shown if this returns false, though if returns true in that case then it is probably only a sliver of the application. If you do, should you check the validity of all fields in the public method before doing so or check at time of use? Any idea how to fix this issue?

Basically i dont know where to put OpenCV code in the fragment as no onCameraFrame method is being implemented by CameraBridgeViewBase. I am trying to make a dynamic string and converting a hardcoded string which has been passed to setText function. Use with to retrieve a for handling management of fingerprints.

Android how to get 'getCurrentInputConnection()' from which is not extended from InputMethodService - There is a text which can be clickable in fragment A and when user click this text , he can go to fragment B.


InputMethodService provides a standard implementation of an InputMethod, which final implementations can derive from and customize. See the base class and the interface for more information on the basics of writing input methods. An input method has significant discretion in how it goes about its work: the provides a basic framework for standard UI elements input view, candidates view, and running in fullscreen mode , but it is up to a particular implementor to decide how to use them. For example, one input method could implement an input area with a keyboard, another could allow the user to draw text, while a third could have no input area and thus not be visible to the user but instead listen to audio and perform text to speech conversion. In the implementation provided here, all of these elements are placed together in a single window managed by the InputMethodService. It will execute callbacks as it needs information about them, and provides APIs for programmatic control over them. Soft Input View Central to most input methods is the soft input view. This is where most user interaction occurs: pressing on soft keys, drawing characters, or however else your input method wants to generate text. Most implementations will simply have their own view doing all of this work, and return a new instance of it when is called. At that point, as long as the input view is visible, you will see user interaction in that view and can call back on the InputMethodService to interact with the application as appropriate. There are some situations where you want to decide whether or not your soft input view should be shown to the user. This is done by implementing the to return true or false based on whether it should be shown in the current environment. If any of your state has changed that may impact this, call to have it re-evaluated. The default implementation always shows the input view unless there is a hard keyboard available, which is the appropriate behavior for most input methods. Candidates View Often while the user is generating raw text, an input method wants to provide them with a list of possible interpretations of that text that can be selected for use. This is accomplished with the candidates view, and like the soft input view you implement to instantiate your own view implementing your candidates UI. Management of the candidates view is a little different than the input view, because the candidates view tends to be more transient, being shown only when there are possible candidates for the current text being entered by the user. To control whether the candidates view is shown, you use. Note that because the candidate view tends to be shown and hidden a lot, it does not impact the application UI in the same way as the soft input view: it will never cause application windows to resize, only cause them to be panned if needed for the user to see the current focus. Fullscreen Mode Sometimes your input method UI is too large to integrate with the application UI, so you just want to take over the screen. Unlike the other UI elements, there is a standard implementation for the extract editor that you should not need to change. The editor is placed at the top of the IME, above the input and candidates views. Similar to the input view, you control whether the IME is running in fullscreen mode by implementing to return true or false based on whether it should be fullscreen in the current environment. If any of your state has changed that may impact this, call to have it re-evaluated. The default implementation selects fullscreen mode when the screen is in a landscape orientation, which is appropriate behavior for most input methods that have a significant input area. When in fullscreen mode, you have some special requirements because the user can not see the application UI. In particular, you should implement to show completions generated by your application, typically in your candidates view like you would normally show candidates. Generating Text The key part of an IME is of course generating text for the application. This is done through calls to the interface to the application, which can be retrieved from. This interface allows you to generate raw key events or, if the target supports it, directly edit in strings of candidates and committed text. Information about what the target is expected and supports can be found through the class, which is retrieved with method. The most important part of this is ; in particular, if this is , then the target does not support complex edits and you need to only deliver raw key events to it. An input method will also want to look at other values here, to for example detect password mode, auto complete text views, phone number entry, etc. When the user switches between input targets, you will receive calls to and. You can use these to reset and initialize your input state for the current target. For example, you will often want to clear any input state, and update a soft keyboard to be appropriate for the new inputType.


Thanks Hi Giovanni, Here is the logcat. XML attributes android:imeExtractEnterAnimation Animation to use when showing the fullscreen extract UI after it had previously been hidden. Use with to retrieve a to manage the device eUICC embedded SIM. Use with to retrieve a for managing battery state. The default implementation returns false when there is no hard keyboard or the keyboard is hidden unless the user shows an intention to use software keyboard. There are no guarantees that this access mode will remain on a file, such as when it goes through a backup and restore.
