in the below xml layout, i have two buttons at the same position and they will do their function based on the visibilty set. now i tried to place two textviews
below the buttons, i want the text views to be below both buttons so I used
android:layout_below="#id/actConnect2_btn_connect"
but at run time when the connect-button is visible the text view appears below it, and if pair-button is visible it overlap
how to display the textview below both buttons?
Note: i know that i can use android:layout:marginTop but i want to solve it without it
code:
<Button
android:id="#+id/actConnect2_btn_pair"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/actConnect2_tv_label_devClass"
android:layout_centerInParent="true"
android:text="#string/str_pair"/>
<Button
android:id="#+id/actConnect2_btn_connect"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/str_connect"
android:layout_below="#+id/actConnect2_tv_label_devClass"
android:layout_alignParentStart="true" />
<TextView
android:id="#+id/actConnect2_tv_label_uuids"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/actConnect2_btn_connect"
android:text="Service's UUID: ">
</TextView>
<TextView
android:id="#+id/actConnect2_tv_uuids"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/actConnect2_tv_label_uuids">
</TextView>
Put both buttons in a LinearLayout then put the textview below the LinearLayout
take both button in one layout
<RelativeLayout android:id="#+id/relativeButton"
android:layout_width="wrap_content"
android:layout_below="#id/actConnect2_tv_label_devClass"
android:layout_height="wrap_content">
<Button
android:id="#+id/actConnect2_btn_pair"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="#string/str_pair"/>
<Button
android:id="#+id/actConnect2_btn_connect"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/str_connect"
android:layout_alignParentStart="true" />
</RelativeLayout>
and use this for your textview
android:layout_below="#id/relativeButton"
You have to place the buttons in a Layout (any type and arrange them accordingly)
Assign an ID to that layout.
Place the textView below that layout ID.

I got a RelativeLayout:
<RelativeLayout
android:id="#+id/RelativeLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<AutoCompleteTextView
android:id="#+id/auto_edit_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center|left"
android:layout_marginBottom="5sp"
android:layout_marginTop="5sp"
android:layout_toLeftOf="#+id/ButtonBackspace"
android:completionHint="#string/a_string"
android:completionThreshold="1"
android:gravity="center"
android:hint="#string/a_string"
android:textAppearance="#android:style/TextAppearance.Large" />
<ImageButton
android:id="#+id/ButtonBackspace"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toLeftOf="#+id/myButton"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:background="#android:color/white"
android:soundEffectsEnabled="true"
android:src="#drawable/dialer_btn_bks" />
<Button
android:id="#+id/myButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:text="New"
android:visibility="gone" />
</RelativeLayout>
The visibility of myButton starts as Gone. I was hoping that when I change the visibility of the button in run time to Visible, it would push the ImageButton and AutoCompleteTextView to the left but both the button and imageButton appear on top of each other since they both got android:layout_alignParentRight="true". I tried adding the android:layout_toLeftOf="#+id/myButton" to the ImageButton but that did not work.
How can I make the button push the other elemets when it become visible and have its own space?
if these elements are just next to each other, you can use a linear layout and set the gravity to right. the linear layout automatically pushes the elements.
in relative layout all elements are "relative" to another element or the parent view, but just to one element for each direction. and if this object is "gone" the relation in this direction also is gone.
I have a Linear layout then programatically I'm adding some spinners and buttons and so on, but I have xml button Wrap content (width) and then on java I add spinner (or anything else) and it goes below this view even if both views are wrap content:
progBar = new ProgressBar(this);
pBarToca = new ProgressBar(this);
pBarToca.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
linToca = (LinearLayout) findViewById(R.id.tetoca);
linToca.addView(pBarToca);
and it's placed under the button of xml:
<LinearLayout android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" android:layout_marginTop="6dp"
android:id="#+id/tetoca">
<TextView style="#style/StylePartida"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/te_toca_jugar" />
<Button android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#A7E9A9" android:onClick="callJugar"
android:text="#string/jugar" />
</LinearLayout>
edit!!!!!!
I want textview on first line then on next line button + progressbar (for example)
You have android:orientation=vertical so the Views will be laid out starting at the top and going down.
If you want them to all be next to each other, remove that from your xml since the default orientation for a LinearLayout is horizontal. If you do this, you will obviously need to change the android:width to wrap_content for your TextView or else it will take up the entire screen.
After your comment, a RelativeLayout would work best here.
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<TextView
style="#style/StylePartida"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/te_toca_jugar"
android:id="#+id/tvID" /> // give it an id
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="6dp"
android:id="#+id/tetoca"
android:layout_below="#/id=tvID"> // place it below the TV
<Button android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#A7E9A9" android:onClick="callJugar"
android:text="#string/jugar" />
</LinearLayout>
</RelativeLayout>
Note the changes in the comments. Now when you add your progressbar to the LL, it should be next to the Button. You may need some changes but this should give you approximately what you want.
<LinearLayout android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="6dp"
android:id="#+id/tetoca">
<TextView style="#style/StylePartida"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/te_toca_jugar"
android:text="#string/te_toca_jugar" />
<Button android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#A7E9A9" android:onClick="callJugar"
android:text="#string/jugar" />
</LinearLayout>
In your textView you are matching the parent
android:layout_width="match_parent"
This will cause the textview to take up the entire width of the parent view.
android:layout_width="wrap_content"
and
android:orientation="horizontal"
android:orientation="vertical" will cause the elements to be stacked.
If you are using "horizontal" it's important not to have a child element with width matching parent.
EDIT:
After OPs change to question:
I have used a textview, two buttons and listview to give you an idea of how you can format it. There are many ways to achieve the same thing, this is one suggestion.
The internal linearlayout has a horizontal orientation (by default).
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="6dp"
android:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="te_toca_jugar"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#A7E9A9"
android:text="jugar"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#A7E9A9"
android:text="jugar2"/>
<ListView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/lv">
</ListView>
</LinearLayout>
</LinearLayout>
Say I have an ImageButton. I want a textview on top of the imagebutton, and centered on it. How would I do this?
you could do it by wrapping both widgets in a FrameLayout
for example:
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<ImageButton
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/image" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/text"
android:layout_gravity="center" />
</FrameLayout>
Use a regular Button, which extends TextView anyway. Then set the background to your image and use setText() to set your text. You can even add icons above, below and/or left & right of the text with the drawableLeft,drawableTop,etc attributes.
You Are overcomplicating your layout. Just add text to the button.
myImageButton.setText("text");
If you really do want to layer these views, you should use a RelativeLayout:
<RealtiveLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageButton
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/img"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/app_name"
android:layout_centerInParent="true"/>
</RelativeLayout>
Make a special note of the attribute layout_centerInParent . this is how the TextView is correctly centered.
I have a basic ListView with two TextViews in the cells and I would like for the TextViews to center to the middle of the Layout when there isn't any text in the other TextView.
Here is my current XML:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:minHeight="80dp"
android:orientation="vertical"
android:gravity="center_vertical"
android:paddingLeft="20dp"
android:paddingRight="20dp" >
<TextView android:id="#+id/titleTextView"
android:textStyle="bold"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="2dp"
android:textSize="16sp"/>
<TextView android:id="#+id/detailsTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="2dp"
android:layout_below="#id/titleTextView"
android:textSize="12sp"/>
</RelativeLayout>
I'm using a RelativeLayout because I am hoping to utilize it when I add more elements, but I want to figure this part out first. Switching to a LinearLayout didn't have any effect on adjusting the TextViews.
Will I have to adjust the views programmatically? If so, how should I handle that? Remove the one view from the layout (Which will require a LinearLayout, right)?
Simply make the TextView "gone" when it is empty, when a view is "gone" it has no effect on the layout it is in, thus the other TextView would center because of the gravity property you have added.
textView.setVisibility(View.GONE);
I am trying to build a UI, where in I have a linear layout which has been defined in the XML.
As per the user's input, I need to add some TextViews to this linear layout. I am able to do this.
My actual problem is, when I have more text views, they are stacked next to each other and some of text views text are hidden or stretched vertically as shown in the image below.
I would like to use the whole width of the linear layout and if the text view can not fit in this row, it should be put in a new row or below the first text view.. I would like the display to be as below.
Following is my Linear layout configuration in XML:
<RelativeLayout
android:id="#+id/RL1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:paddingBottom="5dip"
android:paddingTop="5dip" >
<TextView
android:id="#+id/text1"
android:layout_width="85dip"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:gravity="left"
android:text="Lable 1"
android:textColor="#999999" />
<LinearLayout
android:id="#+id/LL1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_toLeftOf="#+id/button1"
android:layout_toRightOf="#+id/text1"
android:gravity="left|center_vertical"
android:orientation="horizontal"
android:paddingLeft="5dip"
android:paddingRight="5dip"
android:paddingTop="3dip" >
</LinearLayout>
<Button
android:id="#+id/button1"
android:layout_width="30dip"
android:layout_height="30dip"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginTop="2dip"
android:background="#drawable/plus"
android:clickable="true"
android:focusable="true"
android:paddingTop="5dip" />
</RelativeLayout>
Can any one please help me in how to realign the same in java code.
I would Like to suggest you about how you can provide equal sizes to all your views in Linear Layout,you can do that by using weight property in the XML file i.e., android:weight for that particular View and when you use this property you should give width=0dp or 0dip.I think this will solve your problem easily.
Please I suggest you first you take full Knowledge of how to use this property in the following Link:-Weight property with an example
Please see:
How to wrap Image buttons in a horizontal linear layout?
How can I do something like a FlowLayout in Android?
You also might search github for FlowLayout.java.
An alternative approach is given in:
Android - multi-line linear layout
In addition, there's a class that adds images into a TextView:
https://stackoverflow.com/a/21250752/755804
which is not the same as wrapping views in the general case, but sometimes may do the job.
i'm korean.
so i don't speak English well, but i'll help you.
first, Create 'item.xml' with four text boxes.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<CheckBox
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/set_checkbox"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/text2"
android:text="0"
android:layout_weight="1"
android:gravity="center"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/text3"
android:text="0"
android:layout_weight="4"
android:gravity="center"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/text4"
android:text="0"
android:layout_weight="4"
android:gravity="center"/>
</LinearLayout>
second, Create 'main.xml' where 'item.xml' will be dynamically generated.
'orientation' helps to create one line at a time.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
</LinearLayout>
Finally, You can create four TextView per line using the code below.
LinearLayout layout = (LinearLayout)findViewById(R.id.mainxml);
LinearLayout item = (LinearLayout)layout.inflate(this.getContext(), R.layout.itemxml, null);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(MATCH_PARENT, WRAP_CONTENT);
item.setLayoutParams(params);
CheckBox cb = item.findViewById(R.id.set_checkbox);
TextView text2 = item.findViewById(R.id.text2);
TextView text3 = item.findViewById(R.id.text3);
TextView text4 = item.findViewById(R.id.text4);
cb.setChecked(true);
text2.setText("text2");
text3.setText("text3");
text4.setText("text3");
layout.addView(item);
The 10th loop is shown in the following picture.
