我正在为Android开发软键盘。 我想使用InputConnection.commitCorrecrion()更正一些文本,如果按下与Keyboard.KEYCODE_DONE对应的键。 但是,文字没有变化,它只闪一次。 我该如何解决这个问题?
public class SimpleIME extends InputMethodService
implements KeyboardView.OnKeyboardActionListener {
....
@Override
public void onKey(int primaryCode, int[] keyCodes) {
InputConnection ic = getCurrentInputConnection();
switch(primaryCode){
....
case Keyboard.KEYCODE_DONE:
ic.commitCorrection(new CorrectionInfo(oldTextPosition, oldText, newText));
break;
....
}
}
答案 0 :(得分:0)
我有类似的问题,但没有闪光灯,根本没有改变文字。我决定EditText输入只是没有响应这个commitCorrection调用或由于某种原因不接受它,所以我使用了deleteSurroundingText和commitText(我正在替换光标所在的任何单词,如果有的话):
// limit=0 allows trailing empty strings to represent end-of-string split
fun getWordBeforeCursor() : String {
val arr = wordbreak.split(ic.getTextBeforeCursor(255, 0), 0)
Log.d(TAG, "words before: " + arr.joinToString(","))
return if (arr.isEmpty()) "" else arr.last()
}
fun getWordAfterCursor() : String {
val arr = wordbreak.split(ic.getTextAfterCursor(255, 0), 0)
Log.d(TAG, "words after: " + arr.joinToString(","))
return if (arr.isEmpty()) "" else arr.first()
}
fun getCursorPosition() : Int {
val extracted: ExtractedText = ic.getExtractedText(ExtractedTextRequest(), 0);
return extracted.startOffset + extracted.selectionStart;
}
try {
...
val backward = getWordBeforeCursor()
val forward = getWordAfterCursor()
Log.d(TAG, "cursor position: " + getCursorPosition())
Log.d(TAG, "found adjacent text: [" + backward + "_" + forward + "]")
// if in the middle of a word, delete it
if (forward.isNotEmpty() && backward.isNotEmpty()) {
//instead of this:
//ic.commitCorrection(CorrectionInfo(getCursorPosition()-backward.length, backward + forward, icon.text))
//do this:
ic.deleteSurroundingText(backward.length, forward.length)
ic.commitText(newText, 1)
}
