cant type in an EditText android

I have this xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="#dimen/horizontalPadding"
android:paddingRight="#dimen/horizontalPadding"
android:paddingTop="#dimen/verticalPadding"
android:paddingBottom="#dimen/verticalPadding">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:gravity="center_vertical"
android:padding="#dimen/padding" >
<TextView
android:text="#string/training_exercise_set_weight"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textAppearance="?android:attr/textAppearanceMedium" />
<EditText
android:id="#+id/training_exercise_set_weight"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:inputType="numberDecimal"
android:ems="10" />
</LinearLayout>
</LinearLayout>
When my app is running the keyboard is visible and clickable, but the value of editText doesn't change. how can i resolve it?

If someone is interesed, i resolved using the EditText.requestFocus()

Try to replace android:ems="10" with android:maxEms="10" or android:maxLength="10", I'm not sure, what you want to achieve with this parameter
Hope, this will solve you issue

android:ems="10" is all about width of the view, however you are overriding this setting by layout_width property setting to match_parent.
It looks like you would want two EditTexts to be stretch equally and fill that LinearLayout, so here you wouldn't need ems at all. You would need maxLength instead.
Also note that to stretch those EditTexts you should set their widths to 0dp and set their weight to 1 (or something else. They should be equal).
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:gravity="center_vertical"
android:padding="#dimen/padding" >
<TextView
android:text="#string/training_exercise_set_weight"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textAppearance="?android:attr/textAppearanceMedium" />
<EditText
android:id="#+id/training_exercise_set_weight"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:inputType="numberDecimal"
android:maxLength="10" />
</LinearLayout>

For me, the problem was, I didn't let my PopupWindow be focused. Then I found out that my PopupWindow focusable was by default set to false. So, I try to add 1 new parameter that explicitly tells the PopupWindow is focusable. You can see it in my screenshot below. Previously I didn't pass the false value, only the first three values.
Now, I can type anything in the EditText. This one took a whole day to be resolved. 🤣

How to create an EditText of dynamic fixed width

I'm working on an app where my xml looks a bit like this:
<TableRow
android:layout_width="match_parent"
android:layout_height="fill_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/receiver_name"
android:layout_weight="1" />
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="3"
android:maxLength="30"
android:maxLines="1" />
</TableRow>
What I want, is that no matter what device you have, the TextView should take up 1/4th of the width, and the EditText should take up 3/4ths of the width.
As it is now, the code works - until you start typing. The EditText gets wider and wider as you type more and more into it. How do I make it so that my EditText stays the same width that is assigned to it by the layout_weight parameters?

you should use LinearLayout like that :
<LinearLayout
android:layout_width="match_parent"
android:layout_height="fill_parent">
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="#string/receiver_name"
android:layout_weight="1" />
<EditText
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="3"
android:maxLength="30"
android:maxLines="1" />
</LinearLayout>
hope that can help you =)

Just like Janoub said you could use the LinearLayout and weights value.
http://developer.android.com/guide/topics/ui/layout/linear.html
But you can also use table layout with 4 columns so your edittext catches 3 columns and the textview 1.

Why view elements are going out of the page

I have a keyword search option with EditView and a button in my android app, which in ADT looks perfect.
But when i run the program, the EditView expand beyond the viewing area and search button disappears because it goes out of page.
Xml for this is:
<TableRow
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<LinearLayout
android:id="#+id/detail_ll"
style="#style/search_bg_style"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<EditText
android:id="#+id/keyword_detail"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.7"
android:ems="10"
android:hint="#string/keyword" />
<Button
android:id="#+id/button_search"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.3"
android:text="#string/search" />
</LinearLayout>
</TableRow>
Please help me in getting this in viewing area..

can you post the entire xml?
i mean with the
<TableLayout />
main tag
try setting android
android:layout_weight="1"
for both
or try android:layout_weight="1.5"
for edit text and
android:layout_weight="0.5"
for the button

I think you should make the android:layout_width="wrap_content" to android:layout_width="match_parent" or any fixed width (in dps) in the TableRow element.
layout_weight attribute divides a pre-known space according to its weight which is not present in this case.

Here you have to TableRow and LinearLayout height MatchParent and
give Weightsum="1" to LinearLayout it will fixed your problem and also remove android:ems property from Edittext
Hope this Help you.

need help in android layouts

hi i want to create a a layout which must have an EditText and a Sibmit Button in a top of the screen and They should horizontally aligned and filled the whole horizontal space.
whenever i go to portrait or landscape mode it should fill the whole horizontal space. Please guide. m stucked at this point in my application
Thanks

you can try this :
<RelativeLayout android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<Button android:id="#+id/btnSubmit" android:layout_width="wrap_content"
android:text="Submit"
android:layout_height="wrap_content" android:layout_alignParentTop="true"
android:layout_alignParentRight = "true" android:padding = "4dp" />
<EditText android:id="#+id/txtEdit" android:layout_width="fill_parent"
android:layout_toLeftOf="#id/btnSubmit"
android:layout_height="wrap_content" android:layout_alignTop="#id/btnSubmit"
android:layout_alignBottom = "#id/btnSubmit" android:padding = "4dp" />
</RelativeLayout>
hope it helps :)
Note :take a look on this link , it's very helpful for you ;) Understanding User Interface in Android

i m done with that adding a weight= 1 did my work.
<LinearLayout android:id="#+id/rl1" android:orientation="horizontal" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:layout_below="#+id/message" >
<EditText android:id="#+id/search_bar" android:singleLine="true" android:hint="Search"
android:layout_width="fill_parent" android:layout_weight="1" android:layout_height="wrap_content"></EditText>
<Button android:id="#+id/search_submit" android:layout_height="wrap_content" android:layout_width="wrap_content"
android:layout_alignParentRight="true" android:text="Search"></Button>
</LinearLayout>
this works great.. Please vote this answer so that others can also take help.

Making EditText and Button same height in Android

I have an EditText and a Button in my LinearLayout and I want to align them closely together so they see seem to belong together (edittext + micButton for speech input).
Now they don't have the same height and they aren't really aligned well (Button seems to be a little lower than the EditText). I know I can apply a negative margin like -5dp to make them come closer together, but is there perhaps a better way to do this?
Set them in a specific container/layout so that they will automatically have the same height and no margin between them?

Using relative layout you can stretch a view depending upon another views size without knowing the exact size of the other view.
Here is the code :
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
>
<Button
android:layout_width="100dp"
android:layout_height="100dp"
android:text="button"
android:id="#+id/but"/>
<EditText
android:layout_width="100dp"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/but"
android:layout_alignBottom="#id/but"
android:layout_alignTop="#id/but"
/>
</RelativeLayout>
Check this link for reducing space between views :
https://groups.google.com/forum/?fromgroups#!topic/android-developers/RNfAxbqbTIk

Hmm, don't know why people bother so much with tables. Since the both Views are within a LinearLayout (presumable orientation=Horizontal), this command should center both within the layout:
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical" />
</LinearLayout>
Note: Since EditTexts and Buttons may orient their text slightly differently, you may have to do some tweaking (by changing margins or padding) to get the text to align properly.

I hope this solution might help for your scenario...Here is the code..
<RelativeLayout
android:id="#+id/rlLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="15dp"
android:orientation="horizontal"
android:padding="3dp" >
<EditText
android:id="#+id/etId"
android:layout_width="fill_parent"
android:layout_height="50dip"
android:background="#c8c8c8"
android:hint="Edittext"
android:paddingLeft="20dip"
android:paddingRight="10dip"
android:textColor="#000000" />
<RelativeLayout
android:id="#+id/rlLayoutid"
android:layout_width="50dp"
android:layout_height="50dp"
android:layout_alignRight="#+id/etId" >
<Button
android:layout_width="30dp"
android:layout_height="30dp"
android:layout_alignParentRight="true"
android:layout_marginRight="14dp"
android:layout_marginTop="10dp"
android:background="#drawable/calender" />
</RelativeLayout>
</RelativeLayout>

# Daniel Here You can use layout weight and weight sum
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:gravity="center"
android:weight_sum=2
>
<Button
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight=1
android:text="button"
android:id="#+id/but"/>
<EditText
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight=1
/>
</LinearLayout>

Android tries to automatically level everything off of the text and not the buttons themselves.
Took me forever to finally figure it out. Its really simple. Should fix it.
myButton.setGravity(Gravity.CENTER_VERTICAL);
or if they are in a row.. attach the buttons to a table row, then.
myTableRow.setGravity(Gravity.CENTER_VERTICAL);
