下面列出了怎么用android.view.inputmethod.InputConnectionWrapper的API类实例代码及写法,或者点击链接到github查看源代码。
public InputConnection createInputConnection(InputConnection base) {
return base == null ? null : new InputConnectionWrapper(base, true) {
@Override
public boolean sendKeyEvent(KeyEvent event) {
// TODO: this could be improved by working even when we are not empty.
// The behavior should be 'delete isLast character from mPre'.
// In that case, we should check also that getSelectionStart() == 0.
if (!isFirst() && mView.getText().length() == 0 &&
event.getAction() == KeyEvent.ACTION_DOWN &&
event.getKeyCode() == KeyEvent.KEYCODE_DEL) {
removeFromChain(mView);
return false;
}
return super.sendKeyEvent(event);
}
};
}
@VisibleForTesting
public InputConnectionWrapper getInputConnection() {
return mInputConnection;
}
