Button not responding XML issue?

I was working yesterday and not today. Have two buttons one to go back, one that is an emergency button that calls a method to open the dialer for a call to the ambulance.
I think it may be an XML problem not sure was working fine now unresponsive maybe I changed something I shouldn't have. When it was clicking earlier it was saying the method could not be found which I just don't get it as it is in the correct file
ReportActivity.java

incidentReport.setSelection(0);

If you plan on using android:onClick="call"in your xml then you should also have a corresponding function called callin your activity and the logic to perform the click goes inside it.
If you plan on extending the View.onClickListener then inside your override void onClick() you can have a switch statement of your button ids and perform your logic
alternatively you can ignore the first two and get the id of the button and implement the click logic inside the onCreate()

Webview get focus automatically when removing URL from Edit Text

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 xml code.

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
}
}

TextEdit validation overlays show password icon

I have a password TextEdit field that im currently doing validation on and it displays an icon at the end of the TextEdit field to toggle the actual text. When someone enterted in a incorrect password or the passwords dont match it displays an error icon indicating that there was an error with the text entered and this error icon goes right underneath the "show text" icon for the TextEdit field. How do I move either the error icon from validation, or how do I move the "show text" icon?
app displaying both error icon and show text icon

Try these methods to apply validation check:
private TextInputLayout text_email,text_pass, text_confirm_pass;
private EditText email,pass,confirm_pass;
text_pass = (TextInputLayout) findViewById(R.id.input_layout_password);
email = (EditText) findViewById(R.id.email);
private boolean validatePassword() {
if (pass.getText().toString().trim().isEmpty()) {
pass.setError(getString(R.string.err_msg_pass));
requestFocus(text_pass);
return false;
}else if(pass.getText().toString().length()<8) {
pass.setError(getString(R.string.err_msg_pass_length));
requestFocus(text_pass);
return false;
}else {
text_pass.setErrorEnabled(false);
}
return true;
}
To get focus :
private void requestFocus(View view) {
if (view.requestFocus()) {
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
}
}

Screenshots

So here is what I had to do to fix this. I disabled the standard text view of the textEdit by doing the following:
app:passwordToggleEnabled="false"
This will disable the view of the icon to toggle the password visibility. Then What I did was to add an imageView and added my own eye icon to the app:
<ImageView
android:id="#+id/imageView_registerPasswordVisibility"
android:layout_width="24dp"
android:layout_height="24dp"
android:clickable="true"
android:src="#drawable/eye"
android:layout_row="4"
android:layout_column="1"
android:foregroundGravity="center_vertical"
android:layout_gravity="center_vertical" />
I converted my layout to a grid layout and put this image view in the next column to align it to the end of the textEdit, the reason behind this is cause we now show the icon AFTER the textEdit instead of inside the textEdit which where the error validation icon will appear. Doing this will fix the conflict, I handled the imageView to do the same thing as passwordToggle. So here is the entire code for all of that which will also show how to set errors properly on the TextInputLayout if that is what you are using. If not then set errors as you would normally (can be found in standard android documentation):
RegisterActivity.java
public class RegisterActivity extends AppCompatActivity {
//Setup global variables for all of the user interface items.
#InjectView(R.id.wrapper_registerPassword)
TextInputLayout _registerPasswordWrapper; /*this is only needed for when you use TextInputLayout that gives us the ability to have animated hints by default. If you are ONLY using editText then you will not need the code for this wrapper.*/
#InjectView(R.id.editText_registerPasswordInput)
EditText _registerPasswordInput; /*This is to access text that was typed in the editText*/
#InjectView(R.id.imageView_registerPasswordVisibility)
ImageView _registerPasswordVisibility; /*This is used for our image that we will be adding listeners for to do speacial features when the image is pressed. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

I hope this helps out some people, if anyone has anymore questions please let me know and ill help out to the best of my abilities!

If you're looking to only have one icon displayed this could do the trick.
Change the PasswordVisibilityToggleTintMode property.
You can hide the password toggle icon via:
setPasswordVisibilityToggleTintMode(PorterDuff.Mode.CLEAR)
Make it visible again via:
setPasswordVisibilityToggleTintMode(PorterDuff.Mode.MULTIPLY)

Please use app:endIconDrawable="#null" for TextInputLayout in your xml.

First, you need to wrap your edit text in an TextInputLayout.
Then, you should set the errorIconDrawable to null when you set the text error to something, so it won't override the toggle password icon.
Like this:
if (hasError) {
textInputLayout.error = "Error text"
textInputLayout.errorIconDrawable = null
}

It is easier to use:
TextInputLayout.isEndIconVisible
you can show or hide the Eye icon by setting it true or false.
for example when there is an error do this to hide the eye icon so the error icon is visible:
passwordTextInputLayout.isEndIconVisible = false
and then when the user starts typing again show it like this:
passTextView.afterTextChanged {
passwordTextInputLayout.isEndIconVisible = true
}

Layout elements duplicated on Samsung Galaxy Tab 2

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:

Keyboard not shown on inflated editText even after clicking on it

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:layout_centerVertical="true"
android:background="#null"
android:padding="5dp" />
<include
android:id="#+id/removeItemView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
layout="#layout/remove_item_view" />
<EditText
android:id="#+id/fieldEditText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_toLeftOf="#+id/removeItemView"
android:layout_toRightOf="#+id/typeSpinner"
android:ems="10"
android:focusable="true"
android:focusableInTouchMode="true"
android:hint="field"
android:imeOptions="actionDone"
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);
}
});
