I person an Activity successful Android, with 2 parts:
EditTextListView
Once my Activity begins, the EditText instantly has the enter direction (flashing cursor). I don't privation immoderate power to person enter direction astatine startup. I tried:
EditText.setSelected(false);EditText.setFocusable(false);Nary fortune. However tin I convert the EditText to not choice itself once the Activity begins?
Including the tags android:focusableInTouchMode="true" and android:focusable="true" to the genitor format (e.g. LinearLayout oregon ConstraintLayout) similar successful the pursuing illustration, volition hole the job.
<!-- Dummy item to prevent AutoCompleteTextView from receiving focus --><LinearLayout android:focusable="true" android:focusableInTouchMode="true" android:layout_width="0px" android:layout_height="0px"/><!-- :nextFocusUp and :nextFocusLeft have been set to the id of this componentto prevent the dummy from receiving focus again --><AutoCompleteTextView android:id="@+id/autotext" android:layout_width="fill_parent" android:layout_height="wrap_content" android:nextFocusUp="@id/autotext" android:nextFocusLeft="@id/autotext"/>Is the existent job that you conscionable don't privation it to person direction astatine each? Oregon you don't privation it to entertainment the digital keyboard arsenic a consequence of focusing connected the EditText? I don't truly seat an content with the EditText having a direction connected the commencement, however it's decidedly a job to person the softInput framework unfastened once the person did not explicitly petition to direction connected the EditText (and unfastened the keyboard arsenic a consequence).
If it's the job of the digital keyboard, seat the AndroidManifest.xml <act> component documentation.
android:windowSoftInputMode="stateHidden" - ever fell it once getting into the act.
oregon android:windowSoftInputMode="stateUnchanged" - don't alteration it (e.g. don't entertainment it if it isn't already proven, however if it was unfastened once getting into the act, permission it unfastened).
Successful Android improvement, managing direction inside actions is important for a creaseless person education. A communal content arises once an EditText tract robotically positive factors direction upon act commencement. This tin beryllium disruptive, particularly if you privation customers to work together with another parts archetypal. Stopping the EditText from robotically gaining direction requires a fewer antithetic approaches, which we'll research successful item. Knowing however to power direction is indispensable for creating intuitive and person-affable Android purposes, peculiarly once dealing with types oregon analyzable layouts. Fto's dive into the assorted methods to accomplish this.
However to Forestall EditText from Gaining First Direction successful Android Actions
Once an Android act begins, the scheme frequently tries to find the about logical position to direction connected. By default, if an EditText is immediate successful the format, it's a premier campaigner to have first direction, inflicting the keyboard to popular ahead. This behaviour isn't ever fascinating. For illustration, you mightiness privation the person to position any introductory contented oregon work together with a ListView earlier getting into matter. The end is to override this default behaviour and guarantee that nary EditText positive factors direction till the person explicitly interacts with it. We'll expression astatine XML and programmatic options to execute this.
Utilizing XML to Negociate First Direction
1 of the easiest strategies to forestall an EditText from gaining direction connected act commencement is to usage XML attributes successful your format record. This attack entails mounting circumstantial attributes connected genitor layouts to power direction behaviour. The capital attributes we'll usage are focusable and focusableInTouchMode. By cautiously configuring these attributes, you tin guarantee that the direction is directed elsewhere oregon obscurity astatine each once the act archetypal hundreds. This is an effectual manner to negociate the first direction government of your UI with out needing to compose immoderate codification successful your act.
Particularly, you tin adhd the pursuing attributes to the genitor format of your EditText successful the XML record:
android:focusable="true" android:focusableInTouchMode="true" android:clickable="true" Past, adhd these attributes to the genitor format supra that 1:
android:focusable="true" android:focusableInTouchMode="true" android:clickable="true" Adjacent, adhd this to your EditText
android:focusable="false" android:focusableInTouchMode="false" Alternatively, you may besides adhd this to the topmost genitor format:
android:descendantFocusability="beforeDescendants" These strains guarantee that the format positive factors direction earlier immoderate of its kids (together with the EditText), efficaciously stopping the EditText from robotically gaining direction. This attack is cleanable and retains the direction logic straight successful your format explanation.
It is crucial to line that relying connected the complexity of your format and another interactions, you mightiness demand to set these attributes accordingly. Is it conceivable to usage CSS to fractional of a choice? This technique supplies a elemental, declarative manner to negociate direction inside your Android UI.
Programmatically Stopping EditText Direction connected Act Commencement
Piece XML supplies a easy manner to grip first direction, location are conditions wherever programmatic power is essential. This is peculiarly actual once the direction behaviour relies upon connected runtime situations oregon once dealing with dynamically generated UI parts. By utilizing Java oregon Kotlin codification inside your act, you tin exactly power which position has direction (oregon lacks direction) once the act begins. This affords higher flexibility and permits you to accommodate direction behaviour primarily based connected person preferences oregon exertion government.
You tin petition direction for a antithetic position connected the surface, and brand the EditText unfocusable:
EditText editText = findViewById(R.id.yourEditText); LinearLayout parentLayout = findViewById(R.id.parentLayout); //Or any other view editText.setFocusable(false); editText.setFocusableInTouchMode(false); //if you want to disable focus when touching it parentLayout.requestFocus(); An alternate attack is to usage a ViewTreeObserver to perceive for once the format is fit and past broad the direction from the EditText. This ensures that the direction is cleared last the UI has been full initialized. This is utile once another initialization duties mightiness beryllium interfering with the direction direction. You tin past usage clearFocus() connected the EditText to distance direction if it already has it.
Present's however you tin instrumentality that:
final EditText editText = findViewById(R.id.yourEditText); editText.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() { @Override public void onGlobalLayout() { editText.getViewTreeObserver().removeOnGlobalLayoutListener(this); editText.clearFocus(); } }); Take the technique that champion fits your wants, contemplating the complexity of your format and the dynamic necessities of your exertion. Controlling direction programmatically provides you the precision wanted for much analyzable eventualities.
Present’s a examination of the XML and programmatic strategies:
| Characteristic | XML Technique | Programmatic Technique |
|---|---|---|
| Complexity | Elemental, declarative | Much analyzable, requires codification |
| Flexibility | Little versatile | Extremely versatile, tin accommodate to runtime situations |
| Champion Usage Lawsuit | Elemental layouts, static direction behaviour | Dynamic layouts, conditional direction behaviour |
Successful decision, stopping an EditText from robotically gaining direction once an Android act begins tin beryllium achieved done some XML and programmatic means. The prime betwixt these strategies relies upon connected the complexity of your format and the dynamic necessities of your exertion. By utilizing XML attributes similar focusable and focusableInTouchMode, you tin declaratively negociate the first direction government. Alternatively, programmatic power affords much flexibility, permitting you to accommodate direction behaviour primarily based connected runtime situations utilizing the requestFocus() technique and ViewTreeObserver. Careless of the attack, mastering direction direction is indispensable for creating person-affable and intuitive Android purposes.
