how to insert textview with ImageView inside EditText in android dynamically?

I am trying to insert a textview with an imageview inside a Edittext as in below .
can anyone pls give me ideas about how to implement it or something.
thanks :)
update: the textviews in the edittext will vary dynamically
To show textview in android edittext you can try this code..
EditText your_edittext = (EditText)findViewById(R.id.text);
your_edittext.setHint("Your Text");
Now to add image you can do it like this..
Your_edittext.setCompoundDrawables(null, null, getResources().getDrawable(R.drawable.your_image), null

Android : How to adjust Textview

Hello i am trying to display the content i receive in an activity using TextView but it seems that TextView is overlapping a button that i have put in activity's UI.My goal is to put TextView and the button side by side. I have put the TextView in the UI dynamically like this:
String display = extras.getString("EXTRA_MESSAGE");
TextView textView = new TextView(this);
textView.setTextSize(40);
textView.setWidth(20);
textView.setHeight(20);
textView.setText(display);
setContentView(textView);
I know i miss something but i cant find what it is,so can you please suggest a way how to fix that?
Thanks a lot in advance!
When you call setContentView(textView); it changes your layout to just the textView so it isn't overlapping your Button but your Button isn't shown anymore. You need to add it to your layout and put it where you want it.
You can do this by getting a reference to your root View in your xml and calling addView(textVie) on that root View and use addRule() to position your TextView where you want. However, if it isn't necessary to add your TextView dynamically then it is much easier to declare it in your xml.
If you do want to add it dynamically still, then this SO answer, and many more, covers it.

Dynamiclly add a textview using existing textview layout parameters

I am trying to add a TextView from the activity when a button has been pressed. I have found how to add a new textview from the activity, however instead of coding the required layout parameters is it possible to copy an existing textviews parameters (in the xml layout) to the new textview?
I have tried:
TextView tv1 = new TextView(this);
TextView tv2 = (TextView) findViewById(R.id.basetext);;
// its this line below which doesn't work
tv1.setLayoutParams(tv2.getLayoutParams());
But it doesn't copy any of the layout parameters...
Any ideas?
You can do One thing.
If you are trying to set just the Value of the Same TextValue every time and if the Layout properties of that TextView is same at all the time then follow below steps:
First Create the One Layout that only contain he TextView layout only with your appropriate properties. (Let name it as layout_textView.xml)
Now, do add that layout_textView.xml dynamically to your main view as per your requirement.
How it will Solve your issue.
If any query then let me know.
Did you call requestLayout() after adding the textview?

How can I set the text of the TextView within a LinearLayout?

I have created a custom LinearLayout through program which have a custom TextView within it. I have not added the TextView using inflater. Now I want to use this LinearLayout multiple times in XMl layout. But the problem is that how can I set the text of these TextView within the LinearLayout?
Any ideas??
If I right understand it will help you. Good luck!
LinearLayout layout = findViewById(id_linear_layout);
((TextView) layout.findViewById(id_textview)).setText("Text");
When adding the customTextView set the tag using setTag method. And then to retrieve it use linearLayout.findViewWithTag method to retrieve the customTextView and as usual use setText to set the text
You an also alternatively set the id using setId and retrieve it using findViewById method
Use a reference of that TextView to to set the text.
Then add this TextView to LinearLayout.
ex -
TextView text = new TextView(yourActivity.this);
text.setText("Sample Text");
ll.addView(text);
// ll is your LinearLayout.

How to align TextView in android

I am adding Linearlayout dynamically and adding 3 TextView getting the content from webservices for text view if the content of 3 text size is larger it will display in the end of next line .i want display in start line how can i do?
Thanks
TextView header_text;
header_text = (TextView) findViewById(R.id.header_text1);
header_text.setSingleLine();
try to use android:gravity="left" or alignParent="left"
To align your Text inside a specific TextView:
Textview t = (Textview) findViewbyid(R.id.yourView); //refernce to your View
t.setGravity(Gravity.RIGHT); //or any align you want
t.setText("String text or long string");
