Change only lebel EditText to uppercase when using TextInputLayout

I am using the new TextInputLayout from material design library.
I only need to uppercase the Lebel(when positioned up), not the hint.
This is how should looks like
Here is my XML for my TextInputLayout and EditText
<com.google.android.material.textfield.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="#dimen/gap5"
android:hint="#string/user"
>
<com.google.android.material.textfield.TextInputEditText
android:id="#+id/input_user_login"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="textWebEmailAddress"
android:autofillHints="emailAddress"/>
</com.google.android.material.textfield.TextInputLayout>

I don't think you can do this through the XML, I think you can kind of do it programmatically though.
Try something like this:
inputEditText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
inputLayout.setHint(getResources().getString(R.string.your_string_name).toUpperCase());
} else {
inputLayout.setHint(getResources().getString(R.string.your_string_name));
}
}
});

Hint in EditText lefts empty space on focus

I have a EditText with longer multiple lines hint and when I focus on this EditText, hint disappears but lefts empty space around new text which I don't want. I have already tried to fix it with android:gravity="bottom", but empty space still remains.
Here is the code:
<EditText
android:id="#+id/addextra_basedon_value"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10"
android:inputType="textMultiLine"
android:hint="#string/placeholder_acting_on"
android:gravity="bottom" />
And pictures:

after

You can implement the behaviour of the EditText when focused like this:
editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
editText.setHint("");
editText.setText("");
}
}
});

Floating edittext setting alpha value for hint

I am trying to set transparency to hint colour of floating edittext by setting its alpha value to 0.3.But its not working.I don't see any alpha change in hint colour of editext.
Below is the code
<android.support.design.widget.TextInputLayout
android:id="#+id/input_number"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/mobile_email"
android:layout_marginLeft="#dimen/dp15"
android:layout_marginRight="#dimen/dp15">
<EditText
android:id="#+id/number"
android:layout_width="match_parent"
android:layout_height="40dp"
android:textColor="#color/numxtcolor"
android:alpha="0.3"
android:hint="#string/mobilehint"
android:textSize="#dimen/sp16"
android:inputType="number"/>
</android.support.design.widget.TextInputLayout>
mobilenumber.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
mobilenumber.setAlpha(1);
} else {
if (TextUtils.isEmpty(mobilenumber.getText().toString())) {
mobilenumber.setAlpha(0.3f);
}
}
mobilenumber.invalidate();
}
});

I think the problem is that you are calling:
mobilenumber.setAlpha(0.3f);
This way, you are setting alpha for the whole view.. And not for the text.
Maybe, you may change your code as follows:
mobilenumber.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
// Fully opaque WHITE color
v.setTextColor(Color.parseColor("#FFFFFFFF"));
} else {
// 70% transparent color
if (TextUtils.isEmpty(mobilenumber.getText().toString())) {
v.setTextColor(Color.parseColor("#55FFFFFF"));
}
}
v.invalidate();
}
});

Setting iconified to false on android SearchView cause view to not be searchable

This question is a follow up to Show android SearchView EditText by default. My SearchView used to work fine until I added android:iconifiedByDefault="false" to the layout. Now, when I click on the icon or type in the search field, no search takes place. Does anyone know how to fix this problem? here is my SearchView as it exists now.
<SearchView
android:id="#+id/search"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:queryHint="#string/search_hint"
android:iconifiedByDefault="false"
android:textSize="16sp" />
I already tried the following:
mSearch.setOnSearchClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
getActivity().onSearchRequested();
//other stuff happen here
}
});

I solved the problem with
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) { ...}
}

i solve this problem by simply adding requestFocus tag in SearchView widget.
<SearchView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/search"
android:clickable="true"
android:queryHint="Enter Song name.."
android:iconifiedByDefault="false">
<requestFocus/>
</SearchView>

Editview press softkey Return, lose focus AND hide keyboard, how?

I'm working on an Android app and I've got 2 editviews and a label. The user can enter 2 values and the label shows some calculation using input from the editviews. What I want is the following;
user enters either value with soft-keyboard
user presses "Return" softkey
editview should lose focus
the soft-keyboard should disappear
textview label should be recalculated
Now, the v.clearFocus only seems to works when there is another widget that can can get focus(?), so I've also added a dummie zero-pixel layout that can 'steal' the focus from the first editview. The Return key works now, but when the user switches focus from edit1 to edit2 by simply tapping then HideKeyboard() crashes. I've tried checking if inputMethodManager==null but that didn't help.
This all feels like I'm hacking to trick Android into doing some common UI behaviour, so I can't help but think that I'm overlooking something here.
Any help would be greatly appreciated. Btw I know this is similar to this question: How to lose the focus of a edittext when "done" button in the soft keyboard is pressed?
But I've tried that and it doesn't work.
So my layout xml is this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="vertical" >
<!-- Dummy control item so that first textview can lose focus -->
<LinearLayout
android:focusable="true"
android:focusableInTouchMode="true"
android:layout_width="0px"
android:layout_height="0px"/>
<EditText
android:id="#+id/editTest1"
android:layout_width="250px"
android:layout_height="wrap_content"
android:inputType="numberDecimal"
android:imeOptions="actionDone" >
</EditText>
<EditText
android:id="#+id/editTest2"
android:layout_width="250px"
android:layout_height="wrap_content"
android:inputType="numberDecimal"
android:imeOptions="actionDone" >
</EditText>
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="test123" />
</LinearLayout>
And the source is this:
public class CalcActivity extends Activity implements OnFocusChangeListener {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tab2_weight);
EditText testedit = (EditText) findViewById(R.id.editTest1);
testedit.setOnFocusChangeListener(this);
testedit.setOnEditorActionListener(new OnEditorActionListener() {
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if(actionId==EditorInfo.IME_ACTION_DONE){
//Clear focus here from edittext
Log.d("test app", "v.clearFocus only works when there are other controls that can get focus(?)");
v.clearFocus();
}
return false;
}
});
}
public void hideSoftKeyboard() {
InputMethodManager inputMethodManager = (InputMethodManager) this.getSystemService(Activity.INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow(this.getCurrentFocus().getWindowToken(), 0);
}
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus == false) {
Log.d("unitconverter", "onFocusChange hasFocus == false");
// update textview label
TextView bla = (TextView) findViewById(R.id.textView1);
bla.setText(String.format("%s + %s", (((EditText) findViewById(R.id.editTest1)).getText()), (((EditText) findViewById(R.id.editTest2)).getText())));
// hide keyboard
hideSoftKeyboard();
}
}
}
