I need to access a text view which is present inside Linear layout and print the text using gettext()?
Layout looks like:
Linearlayout
Linearlayout
Imageview
Relativelayout
Textview
The layouts around your TextView wouldn't matter unless you are playing with their Visibility.
The Activity in which you are accessing your TextView needs its call to:
setContentView(R.layout.yourLayout);
use textView= (TextView) findViewById(R.id.textViewId);
to map your textView and then can
textView.getText()

Create a linearLayoutObject for first layout and then create another object for TextView.
UiObject lLayout = new UiObject(new UiSelector().className(LinearLayout.class.getName()).index(1));
UiObject tView = lLayout.getChild(new UiSelector().className(TextView.class.getName()).index(1));
String tDetails = tView.getText();
Now you can use tDetails for comparison or other purpose.

Is it possible to find the added TextView to update it with other options.
I am adding by this code new TextView with a Button. Now, I want also set a onClickListerner for the dynamically added TextViews. For this I have to find them with findViewById method. But they aren't createt yet.
Can I make this in a other way and if yes, How?
Button hinzufügenButton = (Button) findViewById(R.id.hinzufügen_Button);
hinzufügenButton.setOnClickListener(new Button.OnClickListener() {
public void onClick (View view){
EditText tischName = (EditText) findViewById(R.id.tisch_name_EditText);
TextView tisch = new TextView(getApplicationContext());
tisch.setText(tischName.getText());
tisch.setAllCaps(true);
tisch.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
tisch.setBackgroundColor(Color.parseColor("#9FA8DA"));
tisch.setTextSize(25);
tisch.setId(id);
id++;
LinearLayout tischeAnzeigen = (LinearLayout) findViewById(R.id.tische_LinearLayout);
tischeAnzeigen.addView(tisch);
}
});
Just add the onClickListener as you create your dynamic views
Example:
...
tisch.setId(id);
tisch.setOnClickListener(yourListener);
...
You can use setId to add an id. But you probably don't need to. If you're creating a view dynamically, you have a reference to it when you create it. Just set it on that reference. No need to find it.
I have 4 TextView: " what is your name?", "in some circumstances" ,you might in some circumstances,you might", "________" and " to help user understand why your app needs a permission.For example " and a Edittext.
Now I want create a layout and when I user layout add view in my class ( not file.xml ) it can show same :
I used custom layout same here : Custom RowLayout and add view in code :
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main22);
int permissionCheck =
rowLayout = (RowLayout) findViewById(R.id.row);
TextView tv1 = new TextView(this);
tv1.setText("what is your name?");
rowLayout.addView(tv1);
EditText ed1 = new EditText(this);
ed1.setWidth(50);
rowLayout.addView(ed1);
TextView tv2 = new TextView(this);
tv2.setText(" in some circumstances ,you might in some circumstances,you might");
rowLayout.addView(tv2);
TextView tv3 = new TextView(this);
tv3.setText("_____");
rowLayout.addView(tv3);
TextView tv4 = new TextView(this);
tv4.setText("to help user understand why your app needs a permission.For example");
rowLayout.addView(tv4);
<convert.htv.ex.convertdata.RowLayout
android:id="#+id/row"
android:layout_width="match_parent"
android:layout_height="wrap_content"></convert.htv.ex.convertdata.RowLayout>
and result
You can see two problems in here:
1. Edittext not in line with text view.
2. when string text length it create a new line. I want a part off textview will show in old line and when end of the line it will show the rest of textview in newline ( sample picture 1).
How I can do it? please help me.
1)Answer for first problem,
add this line of code
tv1.setGravity(Gravity.CENTER)
2) Change this
ed1.setWidth(50);
to
ed1.setWidth(ViewGroup.LayoutParams.WRAP_CONTENT);
I've been looking around how to create UI elements purely by code
How can I do this?
RelativeLayout mainLayout = FindViewById<RelativeLayout>(Resource.Id.MainRelativeLayout);
TextView newText = new TextView(this);
newText.Text = "HEY THERE NEW TEXT MADE VIA CODE";
mainLayout.AddView(newText);
// Set our view from the "main" layout resource
SetContentView(Resource.Layout.Main);
Turns out that you need to place your code after setting the content view
/ Set our view from the "main" layout resource
SetContentView(Resource.Layout.Main);
RelativeLayout mainLayout = FindViewById<RelativeLayout>(Resource.Id.MainRelativeLayout);
TextView newText = new TextView(this);
newText.Text = "HEY THERE NEW TEXT MADE VIA CODE";
mainLayout.AddView(newText);
oh and you do need to specify the type under FindViewById< TYPE >
I am dynamically adding a textView into a layout and giving it ID's. Based on some conditions I want to change the text of the TextView based on its ID assigned.
Something like this: personOne.setText("abcd"); where personOne.id = buttonID;
personOne = new TextView(this);
int buttonID = 2000 + personCount;
personOne.setTextAppearance(this, R.style.button_text);
personOne.setTextColor(getResources().getColor(R.color.red));
personOne.setTextSize(15);
personOne.setText(personAdded);
personOne.setId(buttonID);
Help / Suggestions much appreciated.
Thank you
Use something like this:
TextView tv = (TextView) findViewById(yourId);
tv.setText("abcd");
Assuming the TextView is a child of the Activity's content view.
You can use the buttonID to find and manipulate TextView dynamically as follows:
TextView dynamicTextView = (TextView) findViewById(buttonID);
dynamicTextView.setText("The text you want to set");
in my app when the activity get loaded, i am doing the following
setContentView(R.layout.main2);
layoutToAdd = (LinearLayout) findViewById(R.id.linearLayout1);
for(i=0; i<num;i++)
{
LayoutInflater inflater = LayoutInflater.from(getApplicationContext());
View view = inflater.inflate(R.layout.camera, null);
layoutToAdd.addView(view);
}
The value of num differs for each time.
In my LayoutInflater layout i have a text view, edit text and a button.
Now they are shown according to the number of times mentioned in num, now for each time i want the text and button name to be changed. How to set the text for TextView and Button.
Just set them after you inflate the layout
View view = inflater.inflate(R.layout.camera, null);
TextView tv = view.findViewById(R.id.textviewid); //id defined in camera.xml
Button b = view.findViewById(R.id.buttonid); //id defined in camera.xml
tv.setText();
b.setText();
layoutToAdd.addView(view);
What I suggest it,you should create an xml file containing just a LinearLayout.
Then programaticall,you should create TextViews,EditTexts and Buttons and add it to LinearLayout.
You can set different properties of those components like below:
Here is example of setting TextView's properties.For rest of the components,you can set the same.
TextView tv=new TextView(context);
tv.setBackgroundResource(R.drawable.textview_bg);
tv.setPadding(20, 5, 40, 5);
tv.setText("set your text");
tv.setLayoutParams(new Gallery.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
tv.setTextColor(Color.RED);
tv.setClickable(true);
tv.setId(id);//where id is an integer which should be unique for each TextView
layout.addView(tv);
Also you need to create and add all these three component inside the for loop,providing unique ids depending on i you use to iterate the loop!And you can have a String array for textviews and buttons to set their names in for loop,which would be easier for you for passing the string you like to set to them in loop.
You must store the reference of the view inflated and store in a List then when you want to modify simply list.get(2).findViewById(R.id.textbox_id).
Hope it help.
