Cannot hide Android soft keyboard even with inputmanager

Question

Problem:

I want to hide the keyboard when the button "Add" is pressed. There are two EditText on the screen. The keyboard doesn't appear at starting the activity, which is good, but it doesn't go away on clicking button.

Here are all the possible questions from Stack Overflow that I have seen whose answers don't help me:

Close/hide the Android Soft Keyboard

Programmatically Hide/Show Android Soft Keyboard

How to hide Soft Keyboard when activity starts

How to hide soft keyboard on android after clicking outside EditText?

and many others.

Here is my code:

AddActivity

public class AddActivity extends ActionBarActivity {
EditText text1,text2;
DbHelper db;
ListView l;
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_add);
    db = new DbHelper(this);
    l = (ListView) findViewById(R.id.listInAddActivity);
    text1 = (EditText) findViewById(R.id.i1);
    text2 = (EditText) findViewById(R.id.i2);
//        text1.setInputType(InputType.TYPE_NULL);
  //      text2.setInputType(InputType.TYPE_NULL);
    hideKeyboard();

    loadDataInAdd();

}
public void addNewTask(View view) {
    String s1 = text1.getText().toString();
    String s2 = text2.getText().toString();
    db.addData(s1,s2);
    loadDataInAdd();
    hideKeyboard();
}
public void loadDataInAdd()
{
    try {
        Cursor cursor = db.fetchData();

        ListAdapter myAdapter = new SimpleCursorAdapter(this, R.layout.tasks,
                cursor,
                new String[]{db._ID, db.COLUMN_1, db.COLUMN_2},
                new int[]{R.id.idnum, R.id.c1, R.id.c2}, 0);
        l.setAdapter(myAdapter);
    }
    catch(NullPointerException e)
    {
        e.printStackTrace();
    }
  //  MainActivity.loadData();
}
private void hideKeyboard() {
    // Check if no view has focus:
    View view = this.getCurrentFocus();
    if (view != null) {
        InputMethodManager inputManager = (InputMethodManager) this.getSystemService(Context.INPUT_METHOD_SERVICE);
        inputManager.hideSoftInputFromWindow(view.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
    }
}

}

Most answers are about the InputManager method, but it does not work for me, i.e., does not hide the keyboard when clicking on the button. Here is another variation of InputManager I used:

View view = this.getCurrentFocus();
    if (view != null) {
        InputMethodManager inputManager = (InputMethodManager) this.getSystemService(Context.INPUT_METHOD_SERVICE);
        inputManager.hideSoftInputFromWindow(view.getWindowToken(), 0);

I also tried this:

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

and this does not work either (keyboard isn't hidden on clicking button).

I have also tried:

     <activity android:name=".AddActivity"
              android:label="@string/app_name"
              android:parentActivityName=".MainActivity"
        android:windowSoftInputMode="stateAlwaysHidden">

    </activity>

and

   <activity android:name=".AddActivity"
              android:label="@string/app_name"
              android:parentActivityName=".MainActivity"
        android:windowSoftInputMode="stateAlwaysHidden">

    </activity>

With this one, my app stopped working:

   InputMethodManager inputManager = (InputMethodManager)
            getSystemService(Context.INPUT_METHOD_SERVICE);

    inputManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(),
            InputMethodManager.HIDE_NOT_ALWAYS);

This one totally hid the keyboard (the keyboard did not appear even when the editText was clicked):

text1.setInputType(InputType.TYPE_NULL);
text2.setInputType(InputType.TYPE_NULL);

Answer 1

I decided to use an onclicklistener for my button, instead of using another function and calling it via onClick in AddActivity.xml.

I was halfway through my question when I decided to try using OnCliCkListener once again. After several random tries, the following is the final code that works for me:

btn.setOnClickListener(new View.OnClickListener() {


        public void onClick(View v) {
            // TODO Auto-generated method stub

                InputMethodManager inputManager = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
                inputManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);

        }
    });

Another way is to use OnClickListener in the following manner:

    private View.OnClickListener mListener = new View.OnClickListener() {
    public void onClick(View v) {
        // do something when the button is clicked

        //public void onClick(View v) {

            try {
                InputMethodManager inputManager = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
                inputManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
            } 
 catch (Exception e) {
      e.printStackTrace();
            }

    }
};

Important points for beginners like me:

• The above code should be placed before protected void onCreate(Bundle savedInstanceState)

• To call the above, place this code in protected void onCreate(Bundle savedInstanceState):

  btn.setOnClickListener(mListener);

• Use try-catch for exception handling in both methods (onClickListener, setOnClickListener)

Upon searching for why onClick, the XML attribute doesn't work for me, while OnClickListener does, I have found the following links useful:

setOnclickListener vs OnClickListener vs View.OnClickListener

Android onClick in XML vs. OnClickListener

How exactly does the android:onClick XML attribute differ from setOnClickListener?

Difference between OnClick() event and OnClickListener?

Now, halfway through my answer, I realized my mistake in using the onClick from XML. Here is what I did to get rid of the OnClickListeners:

• First, I moved the part of my code which hid the keyboard into the method in onClick. Here in my case, I moved the entire code inside hideKeyboard() to addNewTask.

Some important points regarding using onClick

• The method should be public and void.

• It should take a View parameter, such as View V.

Finally, the code that works:

  public void addNewTask(View view) {
    String s1 = text1.getText().toString();
    String s2 = text2.getText().toString();
    db.addData(s1, s2);
    loadDataInAdd();
  //  hideKeyboard(); below is the code to hide keyboard
    if (view != null) {
        InputMethodManager inputManager = (InputMethodManager) this.getSystemService(Context.INPUT_METHOD_SERVICE);
        inputManager.hideSoftInputFromWindow(view.getWindowToken(), 0);
    }
}

Summary

I found 3 ways to hide soft keyboard for my case, using:

• OnClickListener :

  private View.OnClickListener mListener = new View.OnClickListener() {
  public void onClick(View v) {
      // do something when the button is clicked
  
      //public void onClick(View v) {
  
          try {
              InputMethodManager inputManager = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
              inputManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
          } 
  
     catch (Exception e) {
    e.printStackTrace();
          }
  
  }
  };
  

• setOnClickListener:

    btn.setOnClickListener(new View.OnClickListener() {
  
  
      public void onClick(View v) {
          // TODO Auto-generated method stub
  
              InputMethodManager inputManager = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
              inputManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
  
      }
  });
  

• onClick, the XML attribute:

  public void addNewTask(View view) {
  String s1 = text1.getText().toString();
  String s2 = text2.getText().toString();
  db.addData(s1, s2);
  loadDataInAdd();
  //  hideKeyboard();
  if (view != null) {
      InputMethodManager inputManager = (InputMethodManager) this.getSystemService(Context.INPUT_METHOD_SERVICE);
      inputManager.hideSoftInputFromWindow(view.getWindowToken(), 0);
  }
  }
  

Answer 2

this will help you to hide your keyboard on startup until you touch the edit text.

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

in your case, try this

btn.setOnClickListener(new View.OnClickListener() {


        public void onClick(View v) {
             getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN); 

        }
    });
