Soft keyboard on physical device doesn't show when a textbox is clicked

I'm currently using Oppo F7 to test my app that I made using Android Studio. However, when I tested it and I clicked on a textbox (or EditText), the keyboard doesn't show/pop-up. Helpppp..
Note:
- My Oppo F7 is running on Android 8.1.0 (API 27)
- It works on the emulator on my laptop but it's far to laggy for me to test

use like this
public static void showSoftKeyboard(final Context context, final EditText editText) {
try {
editText.requestFocus();
editText.postDelayed(
new Runnable() {
#Override
public void run() {
InputMethodManager keyboard = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
keyboard.showSoftInput(editText, 0);
}
}
, 200);
} catch (NullPointerException npe) {
npe.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
in your activity call on text click
showSoftKeyboard(this, yourEditTextToFocus);

How do I programmatically dismiss a crash dialog?

I'm building a DPC (Device Policy Controller), and one of the issues I'm seeing is that while the Play Store and Play Services are being updated, the Google Contact Sync service crashes -- leaving the typical crash dialog on the screen. Since part of the idea of the initial set up process is to have as little user interaction as possible, how can I dismiss this dialog programmatically (since I seem to be pretty much guaranteed that this will happen)?
I've tried dismissing system dialogs...
ctx.sendBroadcast(new Intent(Intent.ACTION_CLOSE_SYSTEM_DIALOGS));
... but that doesn't seem to do the trick.
Since this is a DPC, anything that requires device ownership/administration is fine.
edit: Usually I have no UI on screen at the time, so if one is necessary please do mention it. Also, preferably the solution should work on at least 6.0+, if not 4.0+.

Try to do it onWindowsFocusChanged method like this for example :
#Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
if (!hasFocus) {
Intent ctx= new Intent(Intent.ACTION_CLOSE_SYSTEM_DIALOGS);
sendBroadcast(ctx);
}
}
I'm not sure about app crash Dialog but maybe it'll help you

AppErrorDialog can be dismissed by broadcasting ACTION_CLOSE_SYSTEM_DIALOGS if Android version is N.
ctx.sendBroadcast(new Intent(Intent.ACTION_CLOSE_SYSTEM_DIALOGS));
However, AppErrorDialog won't be displayed if phone is locked.
public boolean canShowErrorDialogs() {
return mShowDialogs && !mSleeping && !mShuttingDown
&& mLockScreenShown != LOCK_SCREEN_SHOWN;
} // ActivityManagerService

Please try this code.
try {
Class ActivityManagerNative = Class.forName("android.app.ActivityManagerNative");
Class IActivityManager = Class.forName("android.app.IActivityManager");
Method getDefault = ActivityManagerNative.getMethod("getDefault", null);
Object am = IActivityManager.cast(getDefault.invoke(ActivityManagerNative, null));
Method closeSystemDialogs = am.getClass().getMethod("closeSystemDialogs", String.class);
closeSystemDialogs.invoke(am, "DPC close");
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (NoSuchMethodException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
}

Anybody know how to select text in webview in android? not use emulateShiftHeld,since the docs said " This method is deprecated"

I try to select text in webview, after I select text,I need to decide what to do next.not just copy the selected text.I have more choice for user to choose from.I mean, after user selected text in webview,could I prompt out a some button for further? I tried use emulateshiftheld to solve my problem.but google's docs said " This method is deprecated".
also,I can't prompt out some choice button.
you can clck the link to see what I mean. link: https://public.blu.livefilestore.com/y1pHhMR2iyIbQN7uJ2C-9CLLJBosWAZw2r4MvD0qyyTG-QWUM-06i6HFu4Fn4oaWnHMbDyTBOa-CPwN6PwoZNifSQ/select.jpg?download&psid=1

Pasting relevant code from WebView emulateShiftHeld() on Android Newer SDK's
/**
* Select Text in the webview and automatically sends the selected text to the clipboard
*/
public void selectAndCopyText() {
try {
KeyEvent shiftPressEvent = new KeyEvent(0,0,KeyEvent.ACTION_DOWN,KeyEvent.KEYCODE_SHIFT_LEFT,0,0);
shiftPressEvent.dispatch(mWebView);
} catch (Exception e) {
throw new AssertionError(e);
}
}

The question is very old, but for other people here is a solution with javascript for API 19+. Just add this to your WebView:
public void getSelectedText(final SelectedTextInterface selectedTextInterface) {
evaluateJavascript("(function(){return window.getSelection().toString()})()", new ValueCallback<String>() {
#Override
public void onReceiveValue(final String selectedText) {
if (selectedText != null && !selectedText.equals("")) {
//If you don't have a context, just call
//selectedTextInterface.onTextSelected(selectedText);
if (context instanceof Activity) {
((Activity) context).runOnUiThread(new Runnable() {
#Override
public void run() {
selectedTextInterface.onTextSelected(selectedText);
}
});
} else selectedTextInterface.onTextSelected(selectedText);
}
}
});
}
public interface SelectedTextInterface {
void onTextSelected(String selectedText);
}
When you are done with selecting text, just call it with:
webView.getSelectedText(new YourWebView.SelectedTextInterface() {
#Override
public void onTextSelected(String selectedText) {
//Your code here
}
});
I hope this may be useful for some people :-)

How to select text from a webview and not copy it?

I am creating an application which requires a webview.
I want to enable text selection in webview. (I found a few solutions but none of them worked)
Once the webview is selected, it should not be directly copied. I should be able to expand the selection range with handles (It is possible in version 2.3 and later. But I want this on versions lower than 2.3. HTC's browser gives us this option)
Any idea?

recently i solved that
put this function on create or on load in activity
private void emulateShiftHeld(WebView view)
{
try
{
KeyEvent shiftPressEvent = new KeyEvent(0, 0, KeyEvent.ACTION_DOWN,
KeyEvent.KEYCODE_SHIFT_LEFT, 0, 0);
shiftPressEvent.dispatch(view);
}
catch (Exception e)
{
Log.e("dd", "Exception in emulateShiftHeld()", e);
}
}
it will done...

How to determine the current IME in Android?

I have an application where I would like to warn the user if they are not using the default Android softkeyboard. (i.e. they are using Swype or some thing else).
How can I check which input method they currently have selected?

You can get a default IME, use:
Settings.Secure.getString(getContentResolver(), Settings.Secure.DEFAULT_INPUT_METHOD);

InputMethodManager has getEnabledInputMethodList(). You get an InputMethodManager from getSystemService() in your Activity.

Here's a bit of code I used to determine if GoogleKeyboard, Samsung Keyboard, or Swype Keyboard is used. The value returned by reflection for mCurId indicates the IME ID.
Test with the different keyboards/input methods you are looking for to find the relevant one
public boolean usingSamsungKeyboard(Context context){
return usingKeyboard(context, "com.sec.android.inputmethod/.SamsungKeypad");
}
public boolean usingSwypeKeyboard(Context context){
return usingKeyboard(context, "com.nuance.swype.input/.IME");
}
public boolean usingGoogleKeyboard(Context context){
return usingKeyboard(context, "com.google.android.inputmethod.latin/com.android.inputmethod.latin.LatinIME");
}
public boolean usingKeyboard(Context context, String keyboardId)
{
final InputMethodManager richImm =
(InputMethodManager)context.getSystemService(Context.INPUT_METHOD_SERVICE);
boolean isKeyboard = false;
final Field field;
try
{
field = richImm.getClass().getDeclaredField("mCurId");
field.setAccessible(true);
Object value = field.get(richImm);
isKeyboard = value.equals(keyboardId);
}
catch (IllegalAccessException e)
{
}
catch (NoSuchFieldException e)
{
}
return isKeyboard;
}
