How do I Detect if Software Keyboard is Visible on Android Device?
Android有没有办法检测软件(又名“软”)键盘是否在屏幕上可见?
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 .
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
}
else {
// keyboard is closed
}
}
});
尝试这个:
InputMethodManager imm = (InputMethodManager) getActivity()
.getSystemService(Context.INPUT_METHOD_SERVICE);
if (imm.isAcceptingText()) {
writeToLog("Software Keyboard was shown");
} else {
writeToLog("Software Keyboard was not shown");
}
