How do I detect if software keyboard is visible on Android Device or not?
I created a simple class that can be used for this: https://github.com/ravindu1024/android-keyboardlistener. Just copy it in to your project and use as follows:
KeyboardUtils.addKeyboardToggleListener(this, new KeyboardUtils.SoftKeyboardToggleListener()
{
@Override
public void onToggleSoftKeyboard(boolean isVisible)
{
Log.d("keyboard", "keyboard visible: "+isVisible);
}
});
try this:
InputMethodManager imm = (InputMethodManager) getActivity()
.getSystemService(Context.INPUT_METHOD_SERVICE);
if (imm.isAcceptingText()) {
writeToLog("Software Keyboard was shown");
} else {
writeToLog("Software Keyboard was not shown");
}
There is no direct way - see http://groups.google.com/group/android-platform/browse_thread/thread/1728f26f2334c060/5e4910f0d9eb898a where Dianne Hackborn from the Android team has replied. However, you can detect it indirectly by checking if the window size changed in #onMeasure. See How to check visibility of software keyboard in Android?.
This works for me. Maybe this is always the best way for all versions.
It would be effective to make a property of keyboard visibility and observe this changes delayed because the onGlobalLayout method calls many times. Also it is good to check the device rotation and windowSoftInputMode
is not adjustNothing
.
boolean isKeyboardShowing = false;
void onKeyboardVisibilityChanged(boolean opened) {
print("keyboard " + opened);
}
// ContentView is the root view of the layout of this activity/fragment
contentView.getViewTreeObserver().addOnGlobalLayoutListener(
new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
Rect r = new Rect();
contentView.getWindowVisibleDisplayFrame(r);
int screenHeight = contentView.getRootView().getHeight();
// r.bottom is the position above soft keypad or device button.
// if keypad is shown, the r.bottom is smaller than that before.
int keypadHeight = screenHeight - r.bottom;
Log.d(TAG, "keypadHeight = " + keypadHeight);
if (keypadHeight > screenHeight * 0.15) { // 0.15 ratio is perhaps enough to determine keypad height.
// keyboard is opened
if (!isKeyboardShowing) {
isKeyboardShowing = true
onKeyboardVisibilityChanged(true)
}
}
else {
// keyboard is closed
if (isKeyboardShowing) {
isKeyboardShowing = false
onKeyboardVisibilityChanged(false)
}
}
}
});
