I've been developing a simple android application.
It worked fine on several virtual devices and on HTC One S, but when I started it on Samsung Galaxy Tab 2 with Android 4.0.4 all the elements on the layout was duplicated. Its visible with the virtual keyboard and without it.
Here is the Layout file:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="center">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="#string/password_label"
android:layout_gravity="center_horizontal" />
<EditText
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:inputType="textPassword"
android:id="#+id/password_view" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/ok_label"
android:id="#+id/password_confirm"
android:layout_gravity="center_horizontal"
android:onClick="checkPassword" />
</LinearLayout>
And the Activity source code:
public class PasswordActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_password);
Button button = (Button) findViewById(R.id.password_confirm);
if (SharedPreferencesHandler.isPreferenceSet(this, SharedPreferencesHandler.PreferenceKey.PASSWORD_PREFERENCE_KEY)) {
button.setText(R.string.ok_label);
} else {
button.setText(R.string.save_label);
}
EditText editText = (EditText) findViewById(R.id.password_view);
editText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
#Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
boolean handled = false;
if (actionId == EditorInfo.IME_ACTION_DONE) {
checkPassword();
handled = true;
}
return handled;
}
});
}
//some utility methods
}
Here is a screenshot of that bug:

In my first activity when i select the text edit the keyboards appears.
When i write one letter the page scrolls as if the edit text had lost focus (but it didn't) and keyboard stay displayed even if it is not there (if i click approximately on the edit text under the displayed keyboard the keyboard entrance animation start again and everything works). I don't know what to do, look's really like a bug to me. Oh and, the bug only appears on this activity (the first activity to start), Android 8.1 Code and screens :
Edit text before bug
Ghost keyboard (you see it but it is not there, if i click the home button then come back, the keyboard disapeared and i can interract with the button and edit text under)LoginActivity.java:
public class LoginActivity extends AppCompatActivity {
private EditText e;
#Override
protected void onCreate(Bundle savedInstanceState) {

e = findViewById(R.id.name_input);
//if i click button or enter get to nex activity
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
validate();
}
});
e.setOnKeyListener(new View.OnKeyListener() {
public boolean onKey(View v, int keyCode, KeyEvent event) {
if ((event.getAction() == KeyEvent.ACTION_DOWN) && (keyCode == KeyEvent.KEYCODE_ENTER)) {
validate();
return true;
}
return false; // i don't know android that much, but i don't think there is a problem here
}
});
//testing purpose
e.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if (!hasFocus) {
Log.e("ERROR", "LOST FOCUS"); //Never called

Found the solution, it was not related to the code or android. I'm using a Xiomi phone and on the internet it is advised to disable the MIUI Optimisation in the dev options when coding. It was the issue, re-enabling it and rebooting the phone solved the problem. Thanks for the answers !
I given Long Click on Linear layout.Code is given below .Its working on Many devices.but not working on few devices Like Samsung Galaxy Tab E, SM-T561 .
activity_main layout,
<LinearLayout
android:id="#+id/ll_accept"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="0.5"
android:gravity="center">
<ImageView
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_marginLeft="10dp"
android:background="#drawable/ic_accept_24dp" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:text="#string/new_accept"
android:textColor="#color/new_accept_color"
android:textSize="#dimen/new_job_accept_reject_txt_size" />
</LinearLayout>
MainActivity() class,
public class MainActivity extends AppCompatActivity implements View.OnLongClickListener {
...........
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
.....................
llAccept = (LinearLayout) findViewById(R.id.ll_accept);
llAccept.setOnLongClickListener(this);
......................
}
#Override
public boolean onLongClick(View v) {
switch (v.getId()) {
case R.id.ll_accept:
//do your need
break;
}
}
}
longClicklistener need to return boolean, false if a click listener has to still execute after the long click and true if there are no further actions needed
Another solution could be adding clickable, focusable and other attributes like those to the LinearLayout.
I have a popUp window which is called on click of a button in activity, this popup has a edittext inside it, im trying to call search function on hitting enter after typing in EditText.But the control never comes inside OnEditorActionListener i have also tried setOnKeyListener.
This is the code for popup window:
private PopupWindow initiatePopupWindow(int i) {
try {
mInflater = (LayoutInflater) getApplicationContext()
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = mInflater.inflate(R.layout.rowsearch, null);
View viewone = layout.findViewById(R.id.blankone);
View viewtwo = layout.findViewById(R.id.blanktwo);
searchedit = (EditText)layout.findViewById(R.id.search_edit);
// searchedit.setImeActionLabel("Go", KeyEvent.KEYCODE_ENTER);
// mDropdown.setFocusable(true);
// mDropdown.update();
// searchedit.setFocusableInTouchMode(true);
searchedit.requestFocus();
searchedit.setOnEditorActionListener(new TextView.OnEditorActionListener() {
#Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_DONE) {
// Search function to be called here
Log.d("search","search");
searchfunc();
return true;
}
return false;
}
});
layout.measure(View.MeasureSpec.UNSPECIFIED,
View.MeasureSpec.UNSPECIFIED);
mDropdown = new PopupWindow(layout, FrameLayout.LayoutParams.MATCH_PARENT,
FrameLayout.LayoutParams.MATCH_PARENT,true);
mDropdown.showAsDropDown(linearLayout,5,5);
} catch (Exception e) {
e.printStackTrace();
}
return mDropdown;
}
This is the layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
>
<View
android:layout_width="match_parent"
android:layout_height="140dp"
android:id="#+id/blankone">
</View>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="80dp"
android:orientation="vertical"
android:padding="20dp"
android:background="#drawable/white_menu">
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textColorHint="#b5b5b5"
android:id="#+id/search_edit"
android:imeOptions="actionDone"
android:hint="what can we help you find?"/>
</LinearLayout>
<View
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:id="#+id/blanktwo">
</View>
</LinearLayout>
I tried many things like setfocusable(true) but nothing seems to work i want searchfunc(); to be called on hitting the enter key in the EditText.
Adding android:inputType="text" to the EditText solved the issue.
I have one Edit Text, 5 buttons and a Webview. Webview load url when user type url in edit text and tap Go button or hit Enter on soft keyboard.
I have three problems here.
1-WebView loads website for example "www.google.com" but soft keyboard does not hide itself. I want to hide it like other browser do.
2-When user open a specific url and then try to remove it from Edit Text to open a different url, webview start loading that incomplete url and get focus automatically on every letter removing. For example user loads "www.google.com" then he try to remove url from end and as he remove "m", webview try to load "www.google.co" then edit text is out of focus and webview stole focus from it then user have to tap in edit text again to remove url but it tries to load after every letter removing. I need Webview to load url only when user tap on Go button or hit Enter on soft keyboard.
Update (forgot to add third problem, here it is)
3-Where can i check when WebView CanGoBack and CanGoForward because i want to set visibility of Back and Forward buttons to false at startup and enabled these two buttons while they CanGoBack and CanGoForward. Where should i put my piece of code to check these conditions?
I hope you guys can understand what i am trying to say. Sorry for my poor english.

Here is my java code.
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
EditText etUrl;
Button btnGo, btnBack, btnForward, btnClear, btnReload;
WebView wb;
String url;
View v;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
wb = (WebView) findViewById(R.id.wb);
wb.getSettings().setJavaScriptEnabled(true);
wb.getSettings().setUseWideViewPort(true);
wb.getSettings().setLoadWithOverviewMode(true);
wb.setWebViewClient(new ourClient());
etUrl = (EditText) findViewById(R.id.etUrl);
btnGo = (Button) findViewById(R.id.btnGo);
btnBack = (Button) findViewById(R.id.btnBack);
btnForward = (Button) findViewById(R.id.btnForward);
btnClear = (Button) findViewById(R.id.btnClear);
btnReload = (Button) findViewById(R.id.btnReload);
btnGo.setOnClickListener(this);
btnReload.setOnClickListener(this);
btnBack.setOnClickListener(this);
btnForward.setOnClickListener(this);
btnClear.setOnClickListener(this);
etUrl.setOnKeyListener(new View.OnKeyListener() {
#Override
public boolean onKey(View view, int i, KeyEvent keyEvent) {
if (keyEvent.getAction()==KeyEvent.ACTION_DOWN && i==KeyEvent.KEYCODE_ENTER) {
return true;
}
load();
return false;
}
});
}
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btnGo:
load();
break;
case R.id.btnBack:
if (wb.canGoBack())
wb.goBack();
break;
case R.id.btnForward:
if (wb.canGoForward())
wb.goForward();
break;
case R.id.btnReload:
wb.reload();
break;
case R.id.btnClear:
wb.clearHistory();
break;
}
}
public void load(){
url = etUrl.getText().toString();
if (!url.startsWith("http://")) {
url = "http://" + url;
}
try {
wb.loadUrl(url);
wb.requestFocus();
} catch (Exception e) {
Toast.makeText(getApplicationContext(), " " + e, Toast.LENGTH_LONG).show();
}
}
}
use this method to hide the keyboard:
public static void hideSoftKeyboard(Activity context) {
InputMethodManager inputManager = (InputMethodManager) context
.getSystemService(Context.INPUT_METHOD_SERVICE);
if (inputManager != null)
inputManager.hideSoftInputFromWindow(context.getWindow()
.getDecorView().getApplicationWindowToken(), 0);
context.getWindow().setSoftInputMode(
WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
}
call it in your load() method like:
hideSoftKeyboard(MainActivity.this);
For your second question you need to call your method inside the condition like:
etUrl.setOnKeyListener(new View.OnKeyListener() {
#Override
public boolean onKey(View view, int i, KeyEvent keyEvent) {
if ((keyEvent.getAction()==KeyEvent.ACTION_DOWN) && (i==KeyEvent.KEYCODE_ENTER)){
load(); //add it here
return true;
}
return false;
}
});
EDIT
For the webview go back feature: override onKeyDown in your activity and check condition like:
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
// Check if the key event was the Back button and if there's history
if ((keyCode == KeyEvent.KEYCODE_BACK) && wb.canGoBack()) {
wb.goBack();
//show your back button here
return true;
}
// If it wasn't the Back key or there's no web page history, bubble up to the default
// system behavior (probably exit the activity)
//show other buttons
return super.onKeyDown(keyCode, event);
}
You can add the check in your onResume() and load() also and show your button accordingly..
#Override
protected void onResume() {
super.onResume();
if(wb.canGoBack()){
//show back button}
else{
//other button
}
}
Background
I have a form-like activity, which has some views that can be created dynamically upon pressing.
I'm using an xml for each field that is inflated upon clicking on a button.
What I need is that upon choosing to add a new item, it will get focus, scroll if needed, and show the keyboard so that the user can type things into it. The keyboard may be shown upon adding the field or when clicking on the EditText.
The problem
For some reason, on some devices (and I don't think it's even an android version issue) when inflating the new view, the editText within it can get focus but it doesn't show the keyboard, even if it has focus and the user clicks on it.
In such a case, the only way to show the keyboard is to click on another EditText.
I've tested it, and noticed that it doesn't occur when I don't use xml at all, meaning when i create the views only in code.
The question
Why does it occur? What can I do in order to fix it?
I've already tried so many possible solutions, but none work on all devices.
Sample Code
the next code has the described issue on xperia j (android 4.0.4) an galaxy mini (android 2.3.6) .
#Override
protected void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final ViewGroup container = (ViewGroup) findViewById(R.id.LinearLayout1);
final LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
findViewById(R.id.button).setOnClickListener(new OnClickListener() {
#Override
public void onClick(final View v) {
final View view = inflater.inflate(R.layout.field, null);
// using the next code works when using it instead of inflating a layout:
// final EditText editText = new EditText(MainActivity.this);
// editText.setText("item " + container.getChildCount());
container.addView(view);
}
});
}
the field layout file:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/RelativeLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#FFffffff"
android:gravity="center_vertical" >
<Spinner
android:id="#+id/typeSpinner"
android:layout_width="80dp"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"

android:inputType="phone"
android:minWidth="200dp"
android:padding="5dp"
android:singleLine="true"
tools:ignore="HardcodedText" >
<requestFocus />
</EditText>
</RelativeLayout>
the main layout file:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/scrollView"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:id="#+id/LinearLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="click"
tools:ignore="HardcodedText" />
</LinearLayout>
</ScrollView>
EDIT: found a partial solution which won't show the keyboard right away, but at least it will be shown when pressing the editText:
public static void forceFocusOnView(final View view) {
if (view == null)
return;
view.post(new Runnable() {
#Override
public void run() {
view.clearFocus();
view.post(new Runnable() {
#Override
public void run() {
view.requestFocus();
}
});
}
});
}
I'm not sure in a reason of that problem. Could be some missmatches when Android sdk were rewritten in order to match some devices.
So I think that the best solution to you is to show your keyboard manually and do not try to move a train, just take the path of the least resistance:
EditText et=(EditText)this.findViewById(R.id.edit_text);
et.setOnFocusChangeListener(new OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(et, 0);<----------------
}
});
Here you go , man. Wish you luck.
Oh i see...
private EditText et;
private Runnable setFocus;
......
protected void onCreate(...){
.
.
.
setFocus=new Runnable(){
#Override
public void run() {
et.requestFocus();
}
};
}
....
findViewById(R.id.button).setOnClickListener(new OnClickListener() {
#Override
public void onClick(final View v) {
final View view = inflater.inflate(R.layout.field, null);
//try this:
et=(EditText)view.findViewById(r.id.fieldEditText);
et.setOnFocusChangeListener(new OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(et, 0);<----------------
}
});
container.addView(view);
container.requestLayout();<--------------
et.postDelayed(setFocus,300);
}
});
