Hide ImageView when keyboard appears, and show it when keyboard disappear
 How can i hide ImageView when keyboard appears (after pressing on some EditText ).  And then show this ImageView when keyboard is dismissed?  
我认为OnFocusChangeListener对你OnFocusChangeListener可能是正确的。 
editText.setOnFocusChangeListener(new OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        // view/hide ImageView
    }
});
edit_Text.setOnFocusChangeListener(new OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
    if(hasFocus){
        Toast.makeText(getApplicationContext(), "got the focus", Toast.LENGTH_LONG).show();
             // Hide your ImageView
               iv.setVisibility(View.GONE);  // (make the view gone)
    }else
        Toast.makeText(getApplicationContext(), "lost the focus", Toast.LENGTH_LONG).show();
            // Show your ImageView
              iv.setVisibility(View.VISIBLE);
    }
});
