android 键盘上的 DONE 键

Question

我在使用 done/enter/next 密钥时遇到问题。我正在制作 android 软键盘，每当我尝试搜索某些内容时，我都无法做到这一点，因为当我按下 DONE 键时，光标只会移动到下一行。这是我的代码：

XML

<Key android:keyLabel="DONE" android:keyWidth="11.11%" android:codes="-1"/>

JAVA

@Override
public void onKey(int primaryCode, int[] keyCodes) {
    InputConnection ic = getCurrentInputConnection();
    switch(primaryCode){
        case -1:
            ic.sendKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_ENTER));
            break;
        default:
            char code = (char)primaryCode;
            if(Character.isLetter(code) && caps){
                code = Character.toUpperCase(code);
            }
            ic.commitText(String.valueOf(code), 1);
    }
}

示例：如果我在 Google 上搜索某些内容并键入我想要的内容，当我单击完成键时我希望它开始搜索。你能帮我一下吗？提前致谢。

Answer 1

而不是

ic.sendKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_ENTER));

尝试

ic.performEditorAction(EditorInfo.IME_ACTION_GO);

执行的操作应该是在 EditorInfo 上定义的操作，它是在 onStartInputView 方法上传递给您的

要在操作之间切换，请使用：

(sEditorInfo.imeOptions & (EditorInfo.IME_MASK_ACTION|EditorInfo.IME_FLAG_NO_ENTER_ACTION))

希望这对您有所帮助。

代码：

case -1:

    switch (sEditorInfo.imeOptions & (EditorInfo.IME_MASK_ACTION|EditorInfo.IME_FLAG_NO_ENTER_ACTION)) {
        case EditorInfo.IME_ACTION_GO:
            ic.performEditorAction(EditorInfo.IME_ACTION_GO);
            break;
        case EditorInfo.IME_ACTION_NEXT:
            ic.performEditorAction(EditorInfo.IME_ACTION_NEXT);
            break;
        case EditorInfo.IME_ACTION_SEARCH:
            ic.performEditorAction(EditorInfo.IME_ACTION_SEARCH);
            break;
        case EditorInfo.IME_ACTION_SEND:
            ic.performEditorAction(EditorInfo.IME_ACTION_SEND);
            break;
        default:
            ic.sendKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_ENTER));
            break;
    }

    break;

@Override
public void onStartInputView(EditorInfo info, boolean restarting) {
    InputConnection ic = getCurrentInputConnection();
    switch (info.imeOptions & (EditorInfo.IME_MASK_ACTION|EditorInfo.IME_FLAG_NO_ENTER_ACTION)) {
        case EditorInfo.IME_ACTION_GO:
            ic.performEditorAction(EditorInfo.IME_ACTION_GO);
            break;
        case EditorInfo.IME_ACTION_NEXT:
            ic.performEditorAction(EditorInfo.IME_ACTION_NEXT);
            break;
        case EditorInfo.IME_ACTION_SEARCH:
            ic.performEditorAction(EditorInfo.IME_ACTION_SEARCH);
            break;
        case EditorInfo.IME_ACTION_SEND:
            ic.performEditorAction(EditorInfo.IME_ACTION_SEND);
            break;
        default:
            ic.sendKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_ENTER));
            break;
    }
}
@Override
public void onKey(int primaryCode, int[] keyCodes) {
    InputConnection ic = getCurrentInputConnection();
    playClick(primaryCode);
    switch(primaryCode){
        case Keyboard.KEYCODE_DELETE :
            ic.deleteSurroundingText(1, 0);
            break;
        case Keyboard.KEYCODE_SHIFT:
            caps = !caps;
            keyboard.setShifted(caps);
            kv.invalidateAllKeys();
            break;
        case Keyboard.KEYCODE_DONE: // how this case needs to be handled ??
            //ic.sendKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_ENTER));

            break;
        default:
            char code = (char)primaryCode;
            if(Character.isLetter(code) && caps){
                code = Character.toUpperCase(code);
            }
            ic.commitText(String.valueOf(code),1);
    }
}
