Android keyboard user issue

Question

I am currently working on creating a custom keyboard application that will be optimized for the device using DPad as the main input device.

My problem is that when the cursor is in the EditText field and you press down (for example, KEYCODE_DPAD_DOWN), the keyboard does not receive focus and KeyEvents. Nothing happens, or the element under the EditText in question gets focus.

Below is the corresponding code.

Any help would be greatly appreciated. I tried to analyze the SoftKeyboard example as well as KeyboardView.java for tooltips without success.

Thanks Bryan

MyKeyboard.java

public class MyKeyboard extends InputMethodService { private static final String TAG = "MyKeyboard"; private MyKeyboardView mInputView = null; @Override public void onCreate() { super.onCreate(); } @Override public View onCreateInputView() { mInputView = (MyKeyboardView) getLayoutInflater().inflate(R.layout.input, null); // attempts to make this focusable mInputView.setClickable(true); mInputView.setFocusableInTouchMode(true); mInputView.setFocusable(true); mInputView.setEnabled(true); return mInputView; } @Override public View onCreateCandidatesView() { super.onCreateCandidatesView(); return null; } @Override public void onStartInputView(EditorInfo info, boolean restarting) { super.onStartCandidatesView(info, restarting); } @Override public void onFinishInput() { super.onFinishInput(); } @Override public void onDestroy() { super.onDestroy(); } } 

MyKeyboardView.java

 public class MyKeyboardView extends TableLayout implements View.OnClickListener, View.OnFocusChangeListener { private static final String TAG = "MyKeyboardView"; private ArrayList<Character> charList = new ArrayList<Character>(); public MyKeyboardView(Context context) { super(context); populateKeyboard(); this.setOnFocusChangeListener(this); this.setOnClickListener(this); } public MyKeyboardView(Context context, AttributeSet attrs) { super(context, attrs); populateKeyboard(); this.setOnFocusChangeListener(this); this.setOnClickListener(this); } @Override public void onClick(View arg0) { Log.d(TAG, "onClick"); } private void populateKeyboard() { charList.add(new Character(',')); charList.add(new Character('.')); charList.add(new Character('?')); charList.add(new Character('<')); charList.add(new Character('>')); charList.add(new Character((char) 0x2798)); // arrow charList.add(new Character((char) 0x2798)); // arrow charList.add(new Character((char) 0x2798)); // arrow charList.add(new Character((char) 0x005F)); // underscore for(char c = '@'; c < 'Z'; c++) { charList.add(new Character(c)); Log.d(TAG, "char: " + c); } TableRow tr = null; for(int i=0; i<charList.size(); i++) { if(i % 7 == 0) { if(tr != null) this.addView(tr); tr = new TableRow(this.getContext()); tr.setGravity(Gravity.CENTER_HORIZONTAL); } TextView tv = new TextView(this.getContext()); tv.setPadding(21, 2, 21, 2); tv.setText(charList.get(i).toString()); tv.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 22); tv.setTextColor(Color.WHITE); tv.setGravity(Gravity.CENTER); tv.setFocusable(true); tv.setEnabled(true); tr.addView(tv); } if(tr.getChildCount() > 0) this.addView(tr); } @Override public void onFocusChange(View v, boolean hasFocus) { Log.d(TAG, "mInputView onFocusChange " + (hasFocus ? "true" : "false")); } } 

Input.xml

 <?xml version="1.0" encoding="utf-8"?> <com.weirdtuesday.mykeyboard.MyKeyboardView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/input" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:background="#FF000000" android:focusable="true" />

Key events must be handled manually in the onKey method. To move the cursor, I use this:

 if (primaryCode == KeyEvent.KEYCODE_DPAD_RIGHT) { int position = connection.getTextBeforeCursor(Integer.MAX_VALUE, 0) .length(); final CharSequence selected = connection.getSelectedText(0); if (selected != null) connection.commitText( mComposing.substring(0, mComposing.length() - selected.length()), 1); else connection.commitText(mComposing, 1); connection.setSelection(position + 1, position + 1); }
