How to remove duplicate keys, preview custom Android keyboard

Question

How to remove duplicate keys, preview custom Android keyboard. I used the following method to remove the preview of the keys that I want. But this method does not work for repeated keys. (android: isRepeatable = "true") If the key is not repeated, the following method works.

remove xml key

<Key android:codes="-5" android:keyWidth="13%p" android:keyIcon="@drawable/ic_key_delete_white" android:keyBackground="@color/dark_key_background" android:isRepeatable="true" android:horizontalGap="3.5%p" android:keyEdgeFlags="right"/> 

Input method class

 @Override public void onPress(int primaryCode) { if (primaryCode == -1 || primaryCode == -5){ kv.setPreviewEnabled(false); } } @Override public void onRelease(int primaryCode) { if(primaryCode == -1 || primaryCode == -5){ kv.setPreviewEnabled(true); } } 

Answer 1

Revers flag setPreviewEnabled ..

 public void onCreate() { mInputView.setPreviewEnabled(false); } public void onPress(int primaryCode) { if (primaryCode==-1||primaryCode==-2||primaryCode==-5||primaryCode==-4){ } else { mInputView.setPreviewEnabled(true); } } public void onRelease(int primaryCode) { mInputView.setPreviewEnabled(false); } 

Answer 2

In the following example, we have two repeated keys (space and delete)

STEP 1: set the PreviewEnabled parameter to false in onCreateInputView ():

 kv.setPreviewEnabled(false); 

STEP 2: Add the following if-else statement to onPress ():

 public void onPress(int primaryCode) { if (!(primaryCode==32||primaryCode==Keyboard.KEYCODE_DELETE)) { kv.setPreviewEnabled(true); } else { kv.setPreviewEnabled(false); } } 

STEP 3: set PreviewEnabled to false in onRelease ():

 public void onRelease(int primaryCode) { kv.setPreviewEnabled(false); }

I wrote an answer to this, check it out here fooobar.com/questions/1381873 / ...

To put it here,

Here is a modified Keyboard class

 import android.content.Context import android.inputmethodservice.KeyboardView import android.os.Build import android.support.annotation.RequiresApi import android.util.AttributeSet import android.view.MotionEvent import android.view.View import android.widget.TextView import com.continental.testapplication.utils.dpToPx import java.lang.reflect.Method class ModifiedKeyboardView :KeyboardView{ constructor(context: Context, attrs: AttributeSet):super(context, attrs) constructor(context: Context, attrs: AttributeSet, defStyleAttr:Int):super(context, attrs, defStyleAttr) @RequiresApi(Build.VERSION_CODES.LOLLIPOP) constructor(context: Context, attrs: AttributeSet, defStyleAttr:Int, defStyleRes:Int): super(context, attrs, defStyleAttr, defStyleRes) /** * Return true, if preview is to be shown, false otherwise. If not implemented, * the preview is going to be shown..... */ var keyPreviewIndexListener:((Int)->Boolean) ?= null private val findKeyIndicesMethod:Method = KeyboardView::class.java.getDeclaredMethod( "getKeyIndices",Int::class.java,Int::class.java, (IntArray::class).java).also { it.isAccessible = true } private val previewText:TextView = KeyboardView::class.java.getDeclaredField( "mPreviewText").let { it.isAccessible = true it.get(this) as TextView } override fun onTouchEvent(me: MotionEvent?): Boolean { if(me == null) return super.onTouchEvent(me) when(me.action){ MotionEvent.ACTION_DOWN -> isPreviewEnabled = true MotionEvent.ACTION_MOVE -> { val touchX = me.x - paddingLeft var touchY = me.y.toInt() - paddingTop val verticalCorrection = dpToPx(14f, context) if (touchY >= -verticalCorrection) touchY += verticalCorrection.toInt() val keyIndex:Int = findKeyIndicesMethod.invoke(this, touchX.toInt(), touchY.toInt(), null) as Int isPreviewEnabled = keyPreviewIndexListener?.invoke(keyIndex)?:true if(!isPreviewEnabled){ previewText.visibility = View.INVISIBLE } } } return super.onTouchEvent(me) } } 

Insert as is.

Further in the class where you manipulate the keyboard,

  keyboardView.keyPreviewIndexListener = { it != spaceIndex && it != doneIndex && it != deleteIndex && it != 'your_custom_index' } 

To find indexes, you can simply do the following

  doneIndex = keyboardView.keyboard.keys.indexOfFirst { it.codes[0] == Keyboard.KEYCODE_DONE } 

This will prevent movement. Please add another solution as well.

those.

 override fun onPress(primaryCode: Int) { Log.e("onPress", primaryCode.toString()) checkAndActivatePreview(primaryCode) } override fun onRelease(primaryCode: Int) { Log.e("onRelease", primaryCode.toString()) deactivatePreview() } private fun checkAndActivatePreview(primaryCode: Int) { keyboard.isPreviewEnabled = (primaryCode != 'your_custom_code' && primaryCode != SPACE_KEY_CODE && primaryCode != Keyboard.KEYCODE_DELETE && primaryCode != Keyboard.KEYCODE_DONE) } 

Answer 4

If the key is repeated, the OnRelease method will be called as soon as OnPress is called. Use this code

 @Override public void onPress(int primaryCode) { if (primaryCode == -1 || primaryCode == -5){ kv.setPreviewEnabled(false); }else{ kv.setPreviewEnabled(true); } } @Override public void onRelease(int primaryCode) { }
