那么到了IME部分的流程又是如何的呢？
首先收到configure change的event调用onConfigurationChanged->inputmethodservice.onConfigurationChanged(conf)
@Override public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
boolean visible = mWindowVisible;
int showFlags = mShowInputFlags;
boolean showingInput = mShowInputRequested;
CompletionInfo[] completions = mCurCompletions;
initViews();
mInputViewStarted = false;
mCandidatesViewStarted = false;
if (mInputStarted) {
doStartInput(getCurrentInputConnection(),
getCurrentInputEditorInfo(), true); //调用startinput，创建IME的input
}
if (visible) {
if (showingInput) {
// If we were last showing the soft keyboard, try to do so again.
if (onShowInputRequested(showFlags, true)) {
showWindow(true);
if (completions != null) {
mCurCompletions = completions;
onDisplayCompletions(completions);
}
} else {
hideWindow();
}
} else if (mCandidatesVisibility == View.VISIBLE) {
// If the candidates are currently visible, make sure the
// window is shown for them.
showWindow(false);
} else {
// Otherwise hide the window.
hideWindow();
}
}
}
