soft keyboard doesn't close and freeze when close

Question

SCENARIO

My App is open 3rd party application from Activity C (A->B->C). After, 3rd party application finished it return to my application on Activity C. Everything work fine until only one EditText in Activity C was typing with soft keyboard and I want to close it.

Soft Keyboard freeze and not close, also my app didn't freeze.

• My test device is base on Android KitKat.
• I change to other keyboard both default and custom.. no hope
• I push home button and return to my app again soft keyboard behavior fine.

Here is my Sample XML (which reproduce this bug)

              android:layout_height="fill_parent"
        >
    <Button
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="Go to Activity B"
            android:id="@+id/btnNext"/>

                        android:id="@+id/btnTestMpos"/>

            </LinearLayout>

</ScrollView>

Here is my Sample CLASS (A->B->C just call startActivity)

CLASS ActivityC

public class ActivityC extends Activity {


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_c);

        Button btnTestMpos = (Button) findViewById(R.id.btnTestMpos);
        EditText edtUser = (EditText) findViewById(R.id.edtReceiver);
        btnTestMpos.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                payWithMPOS();
            }
        });
    }

    private void payWithMPOS() {
        //call thire pparty application
    }

    // return from 3rd party application
    protected void onNewIntent(Intent intent) {
        setIntent(intent);
        getResultFromMPOS();
    }

    public void getResultFromMPOS() {
        // extract result from 3rd party applicaiton
    }
}

Answer 1

try thisin your Activity C Java class

ScrollView yourScrollViewName= (Button) findViewById(R.id.yourScrollViewId);
yourScrollViewName.setOnTouchListener(this);

@Override
    public boolean onTouch(View v, MotionEvent event) {
        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(getWindow().getCurrentFocus().getWindowToken(), 0);
        return false;

    }
