How change location of the TextView depending on content

I have two TextView side by side in a LinearLayout horizontally
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:id="#+id/Tx1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Message" />
<TextView
android:id="#+id/Tx2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Time" />
</LinearLayout>
i want when Tx1 text length is fill the line Tx2 go to next line
when now we add to length of the Tx1 , Tx2 is going outside of the view.
how i can fix it?

You most likely will have to do something programmatically with the orientation using a TextWatcher:
yourEditText.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s) {
}
public void beforeTextChanged(CharSequence s, int start, int count, int after) {}
public void onTextChanged(CharSequence s, int start, int before, int count) {
// You would have to define what your max length is.
if(count > maxLength){
myLinearLayout.setOrientation(LinearLayout.VERTICAL);
}
}
});

How to make TextInputLayout with red astrisk mark

I am trying to make mandatory field with the use of TextInputLayout. I used Spannable class but display the hint of TextInputLayout in single color.I want my view to look something like in below link.
https://material.io/guidelines/components/text-fields.html#text-fields-search-filter

I have created the following TextInputEditText to look as similar as possible to the Material Design Text Field.
XML Layout
<android.support.design.widget.TextInputLayout
android:id="#+id/etlayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:counterEnabled="true"
app:counterMaxLength="25">
<android.support.design.widget.TextInputEditText
android:id="#+id/et"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="16dp"
android:layout_marginLeft="-4dp"
android:layout_marginStart="-4dp"
android:layout_marginTop="8dp"
android:textSize="16sp"
android:inputType="text|textCapSentences"
android:singleLine="true"
android:hint="#string/title"
android:textColorHint="#color/transparent38"/>
</android.support.design.widget.TextInputLayout>
Color
<color name="transparent38">#66000000</color>
Java
etlayout = (TextInputLayout)findviewbyid(R.id.etlayout);
TextWatcher twTitle = new TextWatcher() { //Analyzes when the view changes
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
if (true) { //Replace condition with validity test
etlayout.setErrorEnabled(false); //Removes the extra space
etlayout.setError(null); //Removes the error message
} else { //If the text is not valid
etlayout.setErrorEnabled(true); //Makes the space for the error appear
etlayout.setError("Invalid input"); //Shows a message
}
}
#Override
public void afterTextChanged(Editable s) {
}
};
etTitle.addTextChangedListener(twTitle);

how do you hide texts in edit text but still use its function

I am trying to build a first simple app for calculating tips and having trouble.
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="number"
android:id="#+id/editCurrent"
android:layout_row="0"
android:layout_column="0"
android:ems="10"
android:gravity="center_horizontal"
android:layout_columnSpan="2"
android:padding="16dp"
android:maxLength="6"
android:hint="Enter the Amount"
/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/showCurrent"
android:padding="16dp"
android:layout_row="0"
android:layout_column="0"
android:layout_columnSpan="2"
android:gravity="center_horizontal"
/>
and for MainActivity
private final TextWatcher editCurrentWatcher = new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
try {
bill = Double.parseDouble(s.toString()) / 100;
showCurrent.setText(currencyFormat.format(bill));
calculate();
}
catch (NumberFormatException e){
showCurrent.setText("");
bill = 0.0;
}
calculate();
}
#Override
public void afterTextChanged(Editable s) {
}
};
I have a TextView and a EditText, both overlapping each other. One is for putting a bill amount and the other is for displaying that number in number format.
For example, if I put 100 in edit text, it should display $1.00 and actually it does. But the problem is that since there are two text views, both displays the number and as a result, two views are overlapping each other blocking each view.
How do I hide a number of edit text but still be able to use the edit view?

you can try to set it's color to transparent so it's not visible anymore

You can save the value inside of the edit text in a temp variable and clear the editText and fill the TextView with the value.
Why do you want to use two separate view elements for the same value? If the user enter '1000' you can process it and reset the value to '$1,000.00' (or what you want...)

EditText with only numbers,comma,dot

I have been create an edittext in my xml file.HEre is my code:
<EditText
android:id="#+id/IpAdress"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:inputType="numberDecimal"
android:digits="0123456789.," />
The problem is that in my output project it will work only one of the. Only dot or only comma. What is wrong ? In simulator works fine, only in my release doesnt.

I solved my problem with different android : inputType.
<EditText
android:id="#+id/IpAdress"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:inputType="number"
android:digits="0123456789.-,+" />
It works

You may add a textChangedListener to the editText
<editText variable>.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s) {}
public void beforeTextChanged(CharSequence s, int start,
int count, int after) {
}
public void onTextChanged(CharSequence s, int start,
int before, int count) {
String s = <editText variable>.getText().toString();
if(/*your rules here*/)
/* modify your string s*/;
<editText variable>.setText(s);
}
});

cursor in EditText hint does not start from right for Arabic

I'm trying to make EditText with a hint text:
In English "password" .. the cursor is correctly set to the left.
But for Arabic for which the hint is "كلمه المرور" the cursor is always set to the left (the end of the hint) instead of the right.
<EditText
android:id="#id/ETPass"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#id/etUsrName"
android:layout_marginLeft="#dimen/_25sdp"
android:layout_marginRight="#dimen/_25sdp"
android:layout_marginTop="#dimen/_5sdp"
android:background="#drawable/signup_edittext_input"
android:ellipsize="start"
android:gravity="center|right"
android:hint="#string/Password"
android:imeOptions="actionNext"
android:inputType="textPassword"
android:paddingRight="#dimen/_5sdp"
android:singleLine="true"
android:textColor="#color/orange"
android:textColorHint="#color/orange" />
This happens only for android:inputType="textPassword" . Everything works fine for a normal text inputType.

For Android 17 and higher(4.2.+) its working:
android:textAlignment="viewStart"

Try:
android:textDirection="rtl"

xml code
<EditText
android:maxLength="#integer/lockMaxLen"
android:inputType="textPassword"
android:layout_width="180dip"
android:gravity="right|center"
android:hint="#string/lock_pass_hint"
android:layout_height="45dip"
android:id="#+id/lockPassword" />
in oncreate
passwordEditText.addTextChangedListener(new TextWatcher() {
#Override
public void onTextChanged(CharSequence currentDigits, int start,
int before, int count) {
if (passwordEditText.getText().toString().length() == 0)
passwordEditText.setGravity(Gravity.RIGHT);
else
passwordEditText.setGravity(Gravity.LEFT);
}
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void afterTextChanged(Editable s) {
}
});

Use both, to resolve the alignment issue (even in Samsung device also)
android:textAlignment="viewStart"
android:textDirection="rtl"

Maybe I am late, but I faced the same issue. I resolved the issue with the following workaround.
// Get Current language
public static String getCurrentLanguage(Context context) {
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(context);
return prefs.getString(CURRENT_LANGUAGE, "");
}
// Check if the language is RTL
public static boolean isRTL(String locale) {
return TextUtilsCompat.getLayoutDirectionFromLocale(new Locale(locale)) == ViewCompat.LAYOUT_DIRECTION_RTL ? true : false;
}
// Set gravity to the right
private void repositionPasswordTextInArabic(){
if( LocaleSettings.isRTL(LocaleSettings.getCurrentLanguage(this))){
password.setGravity(Gravity.RIGHT);
}
}

editText.setSelection(editText.getText().length());
