Open soft keyboard programmatically

Question

I have used the following lines to display the soft keyboard manually inside the onclick event, and the keyboard is visible.

InputMethodManager inputMethodManager =
    (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
inputMethodManager.toggleSoftInputFromWindow(
    linearLayout.getApplicationWindowToken(),
    InputMethodManager.SHOW_FORCED, 0);

But I'm still not able to open this while the activity gets opened, so are there any solution for this?

In your manifest file, try adding the following to the <activity> that you want to show the keyboard when the activity starts:

android:windowSoftInputMode="stateVisible"

This should cause the keyboard to become visible when the activity starts.

For more options, checkout the documentation.

Please follow the below code. I am sure your problem will be solved.

if (imm != null){
        imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);
   } 

This is works

<activity
    ...
    android:windowSoftInputMode="stateVisible" >
</activity>

or

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);

All I needed was to expose the keyboard, in a very precise moment. This worked for me! Thanks Benites.

    private Handler mHandler= new Handler();

And in the very precise moment:

    mHandler.post(
    new Runnable() {
        public void run() {
            InputMethodManager inputMethodManager =  (InputMethodManager)getSystemService(INPUT_METHOD_SERVICE);
            inputMethodManager.toggleSoftInputFromWindow(yourEditText.getApplicationWindowToken(), InputMethodManager.SHOW_FORCED, 0);
            yourEditText.requestFocus();
        }
    }); 

I have used the following lines to display the soft keyboard manually inside the onclick event.

public void showKeyboard(final EmojiconEditText ettext){
          ettext.requestFocus();
          ettext.postDelayed(new Runnable(){
            @Override public void run(){
              InputMethodManager keyboard=(InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
              keyboard.showSoftInput(ettext,0);
            }
          }
        ,200);
        }

Put that in onResume method:

findViewById(R.id.root_view_of_your_activity_layout).post(
new Runnable() {
    public void run() {
        InputMethodManager inputMethodManager =  (InputMethodManager)getSystemService(INPUT_METHOD_SERVICE);
        inputMethodManager.toggleSoftInputFromWindow(yourEditText.getApplicationWindowToken(),     InputMethodManager.SHOW_FORCED, 0);
        yourEditText.requestFocus();
    }
});

the runnable is needed because when the OS fires the onResume method you can't be sure that all the views where draw, so the post method called from your root layout makes it wait till every view is ready.
