Android Virtual Keyboard not shown

Question

I'm struggling with virtual keyboard on android. The problem is that I can't bring it up/hide it reliably.

Here's a code which refuses to open the keyboard on three devices I tested(ZTE Blade, Galaxy Nexus and Acer A500).

I can hide the keyboard, and I can toggle it, but I can't show it. I could use toggle to show/hide it, but it's not reliable enough (Since there seems to be no way to see if the keyboard is shown or not).

Full code, see if you can make it work:

package com.test.keyboardtest;

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.view.View;
import android.view.inputmethod.InputMethodManager;
import android.widget.Button;
import android.widget.LinearLayout;
import android.widget.TextView;
    public class KeyboardTestActivity extends Activity {
    LinearLayout myLayout = null;
    TextView myView = null;
    Button toggleButton = null;
    Button showButton = null;
    Button hideButton = null;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        myLayout = new LinearLayout(this);
        myView = new TextView(this);
        showButton = new Button(this);
        hideButton = new Button(this);
        toggleButton = new Button(this);

        myLayout.setOrientation(LinearLayout.VERTICAL);
        myLayout.addView(myView); 
        myLayout.addView(showButton);
        myLayout.addView(hideButton);
        myLayout.addView(toggleButton);


        showButton.setText("Show Keyboard");
        showButton.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                mgr.showSoftInput(myView, 0 );
            }
        });

        hideButton.setText("Hide Keyboard");
        hideButton.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                mgr.hideSoftInputFromWindow(myView.getWindowToken(), 0 );
            }
        });

        toggleButton.setText("Toggle Keyboard");
        toggleButton.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);                
                mgr.toggleSoftInput(0,0);
            }
        });
        this.setContentView(myLayout);        
    }
}

Actually detecting whether the keyboard is visible or not isn't that hard: http://stackoverflow.com/questions/2150078/android-is-software-keyboard-shown — Reuben Scratton, Feb 20 '12 at 11:17
Well, the code you suggested doesn't always work. It depends on many factors. For example, setting FLAG_LAYOUT_NO_LIMITS-flag on window prevents me getting onGlobalLayout-events. I could be enabling/disabling that flag whenever needed, but it can be only called from the UI thread. — Habba, Feb 21 '12 at 08:49
Well, *within *the* *scope* *of* *the* *information* *you* *provided*, it would work. You could be jumping up and down on the keyboard while emitting wild monkey shrieks, that would probably cause problems too. — Reuben Scratton, Feb 21 '12 at 09:54

TRY this

To show keyboard:

Activity.this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);

To hide keyboard:

InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE); imm.hideSoftInputFromWindow(editText.getWindowToken(), 0);

Didn't do the trick. It only brings the keyboard up when I resume the activity. – Habba Feb 20 '12 at 11:41
