I want to set the scroll view height, width, margin and set at below the text view and at the right of relative layout. I tried to set only height of scroll view dynamically. But how to set margin of scroll view and how to keep it programmatically at:
android:layout_below="#+id/item_textInspectorName"
android:layout_toRightOf="#+id/rel_out_two"
Here is my XML code
<RelativeLayout> ................
<ScrollView
android:id="#+id/scrollExpand"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_below="#+id/item_textInspectorName"
android:layout_toRightOf="#+id/rel_out_two"
android:layout_marginLeft="7.5dp"
android:layout_marginRight="10dp"
android:layout_marginTop="6dp"
android:background="#android:color/white"
android:fillViewport="true">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<com.example.tazeen.classnkk.ExpandableTextView
android:id="#+id/expandable_text"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:ellipsize="end"
android:text="expand"
android:textColor="#android:color/black"
android:textSize="12sp"
android:textStyle="normal" />
</LinearLayout>
</ScrollView>
</RelativeLayout> ................
And here is my Activity code which is set the height of dynamically .
ExpandableTextView txtRemark = (ExpandableTextView)findViewById(R.id.expandable_text);
int strRemarkLength = strRemark.length();
if(strRemarkLength > 100)
{
txtRemark.setText(strRemark.concat(" ...Less"));
Log.e("", " Lesss !!!");
scrollView.setLayoutParams(new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.FILL_PARENT, 350));
}
else
{
txtRemark.setText(strRemark);
Log.e("", "Not Lesss !!!");
}
Here is my sample
MainActivity.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/colorAccent"

android:layout_width="100dp"
android:layout_height="match_parent"
android:layout_below="#+id/top_textview"
android:text="Left Text"/>
<ScrollView
android:id="#+id/scrollExpand"
android:layout_width="match_parent"

android:text="expand"
android:textColor="#android:color/black"
android:textSize="12sp"
android:textStyle="normal" />
</LinearLayout>
</ScrollView>
</RelativeLayout>
MainActivity.Java
ScrollView scrollView = (ScrollView) findViewById(R.id.scrollExpand);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, 300);
params.setMargins(20, 20, 20, 20);
params.addRule(RelativeLayout.BELOW, R.id.top_textview);
params.addRule(RelativeLayout.RIGHT_OF, R.id.left_textview);
scrollView.setLayoutParams(params);

I'm fairly new to android and xml layouting. I've been trying to make an app, and already done with the programming bit. However i'm stuck on the finalisation of the layout. Really need a hand. My app should look like this:
I've divided the screen in 4 Linear Layouts as I have numbered in the picture as seen below:
<?xml version="1.0" encoding="utf-8"?>

android:background="#color/material_blue_grey_800">
<Button

android:layout_height="wrap_content"
android:id="#+id/btnGoBack"
android:text="Go Back"
android:layout_weight="1"

android:layout_marginRight="5dp" />
<TextView

android:layout_marginLeft="5dp" />
</LinearLayout>

android:layout_width="match_parent"
android:layout_weight="15"
android:layout_height="wrap_content">
</TableLayout>
</LinearLayout>
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
The problem now is that, the second section is filled programmatically and it has a range of rows from 8 to 14. The same for the columns. Every block is a different button which I add with this code:
Lay= (LinearLayout)findViewById(R.id.Section2);
for (int row = 0; row < numberOfRows; row++)
{
LinearLayout Linearrow = new LinearLayout(this);
Linearrow.setOrientation(LinearLayout.HORIZONTAL);
for (int column = 0; column < numberOfColumns; column++)
{
View a = Chosen.blocks[row][column]; //This is a View the extend Button that has no layout properties defined
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT, 1.0f);
a.setLayoutParams(params);
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);
lp.weight = 1.0f;
Linearrow.addView(a, lp);
}
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);
lp.weight = 1.0f;
Lay.addView(Linearrow, lp);
}
I have tried even using a TableLayout and assigning a small image as background so it could get resized with the following code:
TL =(TableLayout)fa.findViewById(R.id.Section2);
for (int i = 0; i < numberOfRows; i++)
{
TableRow tableRow = new TableRow(c);
for(int j = 0; j < numberOfColumns; j++)
{
String s = T[(i * 10) + j];
Block b = new Block(c, s);
//int w = Math.round(c.getResources().getDisplayMetrics().density * 20);
//int h = Math.round(c.getResources().getDisplayMetrics().density * 80);
//b.setLayoutParams(new TableRow.LayoutParams(w, h, 2.0f));
b.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT, TableRow.LayoutParams.WRAP_CONTENT, 1f));
b.setBackgroundResource(R.drawable.g_3);
tableRow.addView(b);
tableRow.setLayoutParams(new android.widget.LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT, 5f));
final Block fb = b;
}
TL.addView(tableRow);
}
When I run the app, I can see that unless I open it on a big screen phone, the content is not visible entirely(as if the height is set fixed manually of the layouts), and since it is not scroll-able, the content is not visible. How can I rearrange or modify the layout so it looks as in the picture above?
Make fixed height of layouts using layout_weight

And in your java class where you add views dynamically, calculate the weights of children accordingly as given below
Lay= (LinearLayout)findViewById(R.id.Section2);
Lay.measure(View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED);
int totalWidth = Lay.getMeasuredWidth();
float rowWeight = 1 / numberOfRows;
int columnWidth = totalWidth / numberOfColumns;
for (int row = 0; row < numberOfRows; row++)
{
LinearLayout Linearrow = new LinearLayout(this);
Linearrow.setOrientation(LinearLayout.HORIZONTAL);
for (int column = 0; column < numberOfColumns; column++)
{
View a = Chosen.blocks[row][column]; //This is a View the extend Button that has no layout properties defined
// height is determined by row's layout weight
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(columnWidth,
LinearLayout.LayoutParams.MATCH_PARENT, 1.0f);
a.setLayoutParams(params);
Linearrow.addView(a);
}
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);
lp.weight = rowWeight;
Lay.addView(Linearrow, lp);
}
I've not tested these, but just might work with few changes that you can figure out once you run this code.
Use
android:layout_weight
attribute to arrange in equal parts in linear layout.
See in the Link
It is better to use View inside ScrollView. Use the below code:-

my xml is like follow I want to add image view and text view programmatically to given xml.
<?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="wrap_content"
android:layout_marginBottom="12dip"
android:text="#string/app_name"
android:textSize="24.5sp" />
</LinearLayout>
but I want output like following programmatically ie a linear layout contain image view and old text view and add that linearlayout below to new textview.
<?xml version="1.0" encoding="utf-8"?>

Try this way,hope this will help you to solve your problem.
main.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/outerLinearLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:padding="25dp" >
<TextView
android:id="#+id/text1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="12dp"
android:text="#string/app_name"
android:textSize="24.5sp" />
</LinearLayout>
MainActivity.java
public class MyActivity extends Activity {
private LinearLayout outerLinearLayout;
private TextView text1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
outerLinearLayout = (LinearLayout) findViewById(R.id.outerLinearLayout);
text1 = (TextView) findViewById(R.id.text1);
LinearLayout innerLinearLayout = new LinearLayout(this);
ImageView imageView = new ImageView(this);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
params.bottomMargin=12;
imageView.setLayoutParams(params);
imageView.setScaleType(ImageView.ScaleType.FIT_XY);
imageView.setImageResource(R.drawable.ic_launcher);
innerLinearLayout.addView(imageView);
TextView textView = new TextView(this);
textView.setTextSize((float) 24.5);
textView.setText("New Text View");
textView.setLayoutParams(params);
outerLinearLayout.removeAllViews();
innerLinearLayout.addView(text1);
outerLinearLayout.addView(textView);
outerLinearLayout.addView(innerLinearLayout);
}
}
change inner layout
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:padding="25dip" >
By
<LinearLayout
android:id="#+id/internal_image_textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:padding="25dip"
android:visibility="gone" >
Then whenEver you want to show just
findViewById(R.id.internal_image_textView).setVisibility(View.VISIBLE)
How come my LinearLayout with dynamically added images won't take parameters ?
LinearLayout ImageView = (LinearLayout) findViewById(R.id.settings);
LinearLayout ImageView2 = (LinearLayout) findViewById(R.id.settings2);
LinearLayout.LayoutParams imagev = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
imagev.topMargin=2;
ImageView image = new ImageView(getApplicationContext());
image.setBackgroundResource(R.drawable.ic_action_discard);
image.setId(Integer.parseInt(listitems.get(n).get("cbid")));
image.setOnClickListener(new OnClickListener() {
#Override
public void onClick(final View v) {
showpopup(v.getId());
}
});
if (listitems.get(n).get("state").toString().equals("1")) {
cb.setChecked(true);
my_checked_layout.addView(cb,params);
cb.setBackgroundColor(Color.argb(255, 184, 239, 220));
cb.setTextColor(Color.rgb(255, 255, 255));
ImageView2.addView(image, imagev);
} else {
cb.setChecked(false);
cb.setBackgroundColor(Color.argb(255, 19, 202, 140));
cb.setTextColor(Color.rgb(255, 255, 255));
my_layout.addView(cb,params);
ImageView.addView(image,imagev);
}
The my_checked_layout(cb, params); does take the other params
my XML, where the images and checkboxes are being set.
the parts that are being used are in both linear layouts with the id's Parent & parent2.

If you want to add margin within the LinearLayout.LayoutParams you can call the setMargin() method of it.
example:
setMargins(135, 176, 0, 0);
where setMargins (int left, int top, int right, int bottom)
<LinearLayout
android:id="#+id/settings"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
/>
fixed it.

row[i] = (RelativeLayout) inflater.inflate(R.layout.reuse,null);
params.setMargins(0, 50, 0, 0);
newsLayout.addView(row[i],params);
text[i]= (TextView) row[i].findViewById(R.id.text);
text[i].setText("AAAAAAA");
}
You can use LinearLayout instead of RelativeLayout for newsLayout and make the orientation as VERTICAL.
And instead of newsLayout =(RelativeLayout)findViewById(R.id.newsLayout);
write: newsLayout =(LinearLayout)findViewById(R.id.newsLayout);
And rest of the code will be as it is.
This will solve your problem.
i would like to create a custom View (subclass of the View class) and use a layout xml resource.
I want something like this:
public class CustomView extends LinearLayout {
public CustomView(Context context) {
super(context);
LayoutInflater mInflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
mInflater.inflate(R.layout.tweet, this, true);
}
This actually creates a View with the right height and width (a ScrollView with a list of those has exactly the expected length and scrollbars) but they are empty (black) even though the xml layout contains a lot of TextViews.
This is my xml layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/tweet"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#ffffff">
<RelativeLayout
android:layout_height="wrap_content"
android:layout_width="match_parent">
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:orientation="horizontal"
android:background="#ffffff">
<TextView
android:text="User"
android:id="#+id/tvusername"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#000000"
android:textStyle="bold">
</TextView>
<View
android:layout_width="5dip"
android:layout_height="1dip">
</View>
<TextView
android:text="userscreenname"
android:id="#+id/tvuserscreenname"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</TextView>
</LinearLayout>
<TextView
android:text="0s"
android:id="#+id/tvtime"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true">
</TextView>
</RelativeLayout>
<TextView
android:text="Tweet Content"
android:id="#+id/tvcontent"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textColor="#000000">
</TextView>
<View
android:layout_width="match_parent"
android:layout_height="1px"
android:background="#ffffff">
</View>
<TextView
android:text="Retweet by"
android:id="#+id/tvrtby"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</TextView>
</LinearLayout>
This is my main layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff"
>
<ScrollView
android:layout_height="match_parent"
android:layout_width="match_parent"
android:id="#+id/scrollView1"
android:orientation="vertical"
android:layout_alignParentTop="true">
<LinearLayout
android:layout_width="match_parent"
android:id="#+id/timeline"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="#ffffff">
<TextView
android:id="#+id/tvoutput"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/hello"
/>
</LinearLayout>
</ScrollView>
</LinearLayout>
This is how I add the custom view to my main view:
Not working (what I try to achieve):
TweetView ctweet = new TweetView(getApplicationContext(),tweet);
timeline.addView(ctweet);
My current solution (works, but uses no custom view):
View vtweet = View.inflate(getApplicationContext(), R.layout.tweet,null);
TextView tvusername = (TextView) vtweet.findViewById(R.id.tvusername);
TextView tvuserscreenname = (TextView) vtweet.findViewById(R.id.tvuserscreenname);
TextView tvcontent = (TextView) vtweet.findViewById(R.id.tvcontent);
TextView tvtime = (TextView) vtweet.findViewById(R.id.tvtime);
tvusername.setText(tweet.getUser().getName());
tvuserscreenname.setText('#' + tweet.getUser().getScreenName());
tvcontent.setText(tweet.getText());
//tvtime.setText(ctweet.tvtime.getText());
timeline.addView(vtweet);
you can use this in your xml just like any other view like <TextView
try <packageName.ClassName ie something like <com.example.CustomView
Probably you have to set the Layout Params of your TweetView object.
LinearLayout.LayoutParams fieldparams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT, 1.0f);
ctweet.setLayoutParams(fieldparams);
