for some reason, my edittext does not show the keyboard when tapped on, i have no idea what is wrong, any help would be greatly appreciated
i have tested this using an emulator and an actual device, but neither work

You need to give a size to you EditText otherwise it's size is 0.
You set it as "wrap_content" and you have no content. So you either set a background drawable to it or put some text or "hint" in it so it will have an actual size.
Just try and put android:layout_width="50dp"
android:layout_height="100"
and see if it works.

Textview items are not visible. The Button below them is.
Tried changing the LinearLayout with RelativeLayout, changed the match_parent and content with 0dp. None of them worked. Only the button shows in the right spot as though the TextViews are there but invisible. These views are called in the onCreate() of the Activity.

You try to use android:text instead of tools:text. tools:textonly visible in the Android Studio.
Or you should use yourTextView.setText("yourText") if you are using tools:text.
Instead of using tool:text in xml use android:text="abc" in textView.
As tool:text is used for android studio layout preview . It does not show text when you run your application .
While android:text is used to set text to textview, button etc.
Yep, it was all working and just placing android:text showed it.
Thank you very much.
I have created this, with 1 webview and 1 textview (tried also edittext) and a scrollview, but in the preview it explains all lines, when i launch it explain only 1 line. i tried to rmeove scrollview, webview...nothing...how can i do? Thank you

</ScrollView>
Preview on Android Studio
Preview on my Phone/Emulator
In strings.xml you must escape all ' of testonavi_spawnby \', for example: ...all\'Avamposto...
Take a look into the documentation for String resources.
Edittext height is given as 126dp. You'll not be able to see 30 lines in it. so make the layout_heigh of the edittext as "wrap_content". This will make the edittext dynamic. As the total content is in scrollview, you'll still be able to scroll and see the complete content
Did you try using
android:minLines=10
where 10 is the number of lines you want it to appear.
Since you have set the android:width="match_parent" maybe its going beyond the view change it to android:layout_width="wrap_parent".
Change the code to:
<TextView
android:id="#+id/testo"
android:layout_width="wrap_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="15dp"
android:layout_marginRight="15dp"
android:minLines="10"
android:text="#string/testonavi_spawn"
android:textSize="15sp" />
NOTE: Always use a TextView to display the text and EditText to edit any texts.
I have a TextView inside a LinearLayout which displays only a part of its text without wrapping to a newline and cannot understand why. It doesn't even show the ellipsis somewhere.
The TextView
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/import_progress_text"
android:singleLine="false"
android:maxLines="4"
android:ellipsize="end"
style="#style/TxtDefault" />
i also tried layout_weight=0 along with layout_height=0 but still no luck. All the siblings inside the LinearLayout have layout_height=wrap_content set.
EDIT
Okay apparently it works when a fixed width is set, but neither with fill_parent nor with match_parent. Is this the expected behaviour?
Per Request the whole layout
Note that inside the FrameLayout is another invisible one, which is rather long

if you want to always show text in n lines, just add android:lines="n",
or if it's not work, try to use for your TextView ->
android:textAppearance="?android:attr/textAppearanceLarge"
hope that will help.
The code snippet is wrapping to multiline perfectly. There might be some problem with the IDE, which is not previewing properly. Test on a real device.
Hello I am trying to get text to display like it does in terminal or cmd. And by that I mean a window of text that with each input makes a new line and then displays the bottom line of the TextView, and there would be a set amount of lines always on the screen.
It sounded easy to do, but now that I started I'm not sure how to do it.
I tried putting a TextView in a ScrollView like this
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:weightSum="100" >
<ScrollView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1">
<TextView android:id="#+id/tv1"
android:layout_width="wrap_content"
android:minLines="11"
android:maxLines="11"
android:layout_height="wrap_content"/>
</ScrollView>
<EditText
android:id="#+id/editText1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="10" >
<requestFocus />
</EditText>
<Button
android:id="#+id/button1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="10"
android:onClick="buttonclick"
android:text="Button" />
</LinearLayout>
and then
sss=et1.getText().toString();
tv1.append("\n"+sss);
to add new lines
This all works but I really have no idea how to make the TextView go to the bottom, right now it just cuts off when I hit the max number of lines.
I definitely don't expect anyone to write my program for me. I am here to learn
Thanks for your time!
Call fullScroll(View.FOCUS_DOWN) on the ScrollView after appending the text.
I am developing an application for Android.
I have a simple layout. A CheckBox, a Spinner and a Button at the top, a two line EditText at the Bottom which is displayed when the CheckBox is checked and another EditText which covers the rest of the space in the middle.
The problem is that when I am writing on the big EditText, sometimes the layout goes out of the screen on top and as a result I can't see what I am writing.
As a solution, I can set my layout to resize when the keyboard shows (using android:windowSoftInputMode="adjustResize" on the manifest.xml) but that won't be good since I do not want the 2 EditTexts to share the space left on the screen.
My layout code follows:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<Button android:id="#+id/button"
android:text="Push"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_alignParentTop="true"
android:layout_alignParentRight="true"/>
<CheckBox android:id="#+id/check_box"
android:text="Check"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true" />
<Spinner android:id="#+id/spinner"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />
<EditText android:id="#+id/text_2"
android:hint="#string/hint_2"
android:inputType="textMultiLine"
android:maxLines="2"
android:gravity="top"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_alignParentBottom="true"
android:visibility="gone" />
<EditText android:id="#+id/text_1"
android:hint="#string/hint_1"
android:inputType="textMultiLine"
android:gravity="top"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_below="#id/spinner"
android:layout_above="#id/text_2"
android:layout_alignWithParentIfMissing="true" />
</RelativeLayout>
P.S. This thing happens only on my Wildfire and very rare on the Emulator. A friend's Desire HD didn't have any problem at all. I don;t know if this makes any difference...
Thanks in advance for your help.

I have the exact same problem. I've tested and this only happens with EditText in multiline mode and when SoftInputMode is set to adjustPan. This is most probably an Android bug.
The only solution I've found is to remove adjustPan.
