I am working with Android Studio and designing a layout as below. However, my ListView lv_comics only displays enough space for 1 item. I have tried to set layout_height to fill_parent, but it still does not work. However, when I set layout_height to a specific size, it is OK, but this is not good when I switch to another screen size. Anyone can help me?

data_shifted_down
Im creating an android project(java) that pulls data from server and places that data into a table so I have to create a table programmatically. I followed a few examples here but for every column in row its being shifted down...
I attached a pic.

MainActivity.java where it iterates through the data to add to TableRow then add that TableRow into TableLayout:
for (int c = 0; c < a.length; c++) {
final TableLayout detailsTable = (TableLayout) findViewById(R.id.details_table);
View v=getLayoutInflater().inflate(R.layout.tablerow, null);
TableRow tableRow = (TableRow) v.findViewById(R.id.tr);
detailsTable.setStretchAllColumns(true);
TextView tv = null;
switch (c) {
case 0:
tv = (TextView) tableRow.findViewById(R.id.tableCell1);
break;
case 1:
tv = (TextView) tableRow.findViewById(R.id.tableCell2);
break;
case 2:
tv = (TextView) tableRow.findViewById(R.id.tableCell3);
break;
case 3:
tv = (TextView) tableRow.findViewById(R.id.tableCell4);
break;
}
tableRow.setGravity(Gravity.CENTER_HORIZONTAL);
tv.setText(a[c]);
tv.setBackgroundColor(Color.parseColor("#f8f8f8"));
tv.setLayoutParams(new
TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT,
TableRow.LayoutParams.MATCH_PARENT));
//new Log("here: ", Integer.toString(tv.getId()));
//Add row to the table
if(tableRow.getParent() !=null){
((ViewGroup)tableRow.getParent()).removeView(tableRow);
}
detailsTable.addView(tableRow);
Tried every solution on the site. Changed to RelativeLayout no luck. Tried gravity and every other attribe...
Looks a horrible way to try and do it but your problem is you are inflating a new tablerow for each item of data with:-
View v=getLayoutInflater().inflate(R.layout.tablerow, null);
who's parent is null
therefore:-
if(tableRow.getParent() !=null){ ((ViewGroup)tableRow.getParent()).removeView(tableRow); }
won't remove a view (not that you should be removing a view)
not tested but something like this might work but for only where a has 4 data items (because you switch statement won't work for anything longer - could also use modulus calculation for that)
View v;
for (int c = 0; c < a.length; c++) {
// Every 4th data item (remainder is zero) e.g. 0,4,8,etc
if ((c%4) == 0) {
// inflate the view
v=getLayoutInflater().inflate(R.layout.tablerow, null);
}
// Rest of your code
....
//Add row to the table
if ((c%4) == 0) {
detailsTable.addView(tableRow);
}
}
I am creating a simple tasklist app, and I want to programmatically add a TextView to an embedded LinearLayout. However, it is not showing up for some reason.
I try to add the TextView in MainActivity (irrelevant code removed).
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
setIntent(intent);
processExtraData();
}
private void processExtraData(){
Integer hours = 4;
Integer minutes = 35;
Integer seconds = 0;
LinearLayout linearLayout = (LinearLayout) findViewById(R.id.linlayout);
TextView txt1 = new TextView(this);
final float scale = this.getResources().getDisplayMetrics().density;
int pixels = (int) (64 * scale + 0.5f);
ViewGroup.LayoutParams params = new LinearLayout.LayoutParams(0, pixels, 1f);
txt1.setLayoutParams(params); txt1.setText(hours.toString()+":"+minutes.toString()+":"+seconds.toString());
linearLayout.addView(txt1);
}
The embedded LinearLayout is declared in activity_main:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

I have already tested and made sure that onNewIntent and processExtraData are called. No errors are thrown either. Could this be a GUI issue? Any help would be greatly appreciated.
in fact I have the following problem:
I have two ListView loaded automatically with two adapters, the problem is in the XML, both list only displays the first element.

<!--Result of research-->

the problem I think in the ScrollView or something else that flushes to that.
thank you in advance .
You can use this function to display all the items in the listview.
public static void setListViewHeightBasedOnChildren(ListView listView) {
ListAdapter listAdapter = listView.getAdapter();
if (listAdapter == null) {
// pre-condition
return;
}
int totalHeight = 0;
int desiredWidth = MeasureSpec.makeMeasureSpec(listView.getWidth(), MeasureSpec.AT_MOST);
for (int i = 0; i < listAdapter.getCount(); i++) {
View listItem = listAdapter.getView(i, null, listView);
listItem.measure(desiredWidth, MeasureSpec.UNSPECIFIED);
totalHeight += listItem.getMeasuredHeight();
}
ViewGroup.LayoutParams params = listView.getLayoutParams();
params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
listView.setLayoutParams(params);
listView.requestLayout();
}
Example:
setListViewHeightBasedOnChildren(yourlistview);
I'm just trying to add spinners dynamicallyand I found my way here Add Spinner dynamically in a loop
that works good but my issue is the view takes place instead of my original layout (a header, a footer and an image view).
I would like to place it in a specific layout in the xml file, between the header and the footer for example.
Is there a way to do this?
my code
protected void onCreate(Bundle savedInstanceState) {
Intent i = getIntent();
conteneur = "container No : " + i.getStringExtra("container");
conteneur_s = i.getStringExtra("container");
fichano = i.getStringExtra("fichano");
pos = i.getIntExtra("pos", 0);
latitude = i.getDoubleExtra("geolat", 0);
longitude = i.getDoubleExtra("geolon", 0);
volume = i.getStringExtra("volume");
saver = i.getStringExtra("saver");
poids = i.getStringExtra("poids");
tel = i.getStringExtra("telpass");
driver = i.getStringExtra("driverpass");

I'm not terribly sure here, I wonder if it is replacing the view because you aren't setting a unique ID for each view? That or failing to call layout.invalidate() after finishing a run through the loop.
My button component takes space of my custom view class,if i put more it takes up more space,any reason why is that
My oncreate method :
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_control);
MyCustomPanel view = new MyCustomPanel(this);
DisplayMetrics metrics;
metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
int height = getDPI(500, metrics);
int width = getDPI(800,metrics);
layout = (LinearLayout) findViewById(R.id.r2) ;
layout1 = (LinearLayout) findViewById(R.id.l2);
ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(width,
height);
layout.addView(view,params);
}
This is my xml code :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"

these are the screen shots
Additionally is there anyway to set gravity of my custom view.??
Update your layout with this code.
