setText in custom view

Question

I have created a custom class from a tutorial online. It works fine, but what I want to do is make it so that I can set the text of the view, just like I would any other view. How is that accomplished. Here is the xml for the custom view

<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center">
<ImageView
android:id="@+id/file_image_holder"
android:layout_width="110dip"
android:layout_height="110dip"
android:src="@drawable/pdf_icon" />
<TextView
android:id="@+id/file_name_holder"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="File Name Here" />
</LinearLayout>

What I am trying to achieve is this

FileView fileView = new FileView(this)
fileView.setText("text")

Answer 1

TextView filename = (TextView)findViewById(R.id.file_name_holder);
filename.setText("someFile.exe");

On another note ... you can use hint to give your users a greyed out text prompt that they won't have to erase when entering a filename. In your XML replace android:text with android:hint for your TextView.

Answer 2

replace "File Name Here" with "TEXT YOU WANT" or @string/name_of_string_in_string.xml

or the java way, which someone else answered

Answer 3

here no_internet is include xml view . in the include view contain text view. you can set text in include custom text view like ....

 no_internet     = view.findViewById(R.id.no_internet);
  ((TextView) no_internet).setText(R.string.no_internet_connection);

I didnt understand your full requirement. But if you want to create a custom view the following things you should do:

For eg: If you want to create a button using your custom layout, then

1. Create a class that extends a layout.

   public class MyCustomView extends RelativeLayout {
   
           private Button customBtn;
   
           public MyCustomView(Context context, AttributeSet attrs) {
                super(context, attrs);
                        init(context);
           }
           private void init(Context context) {
                customBtn = new Button(context);
                customBtn.setText("Button");
                RelativeLayout.LayoutParams buttonParams = new RelativeLayout.LayoutParams(android.view.ViewGroup.LayoutParams.WRAP_CONTENT, android.view.ViewGroup.LayoutParams.WRAP_CONTENT);
                buttonParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
                buttonParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
                addView(customBtn, buttonParams);
       }
   }
   

If you want to add any listeners, implement and override it.

2.Mention this custom layout inside your xml as: (my MyCustomView is present in com.android package)

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" android:layout_height="fill_parent" >

            <com.android.MyCustomView android:background="@android:color/white" android:id="@+id/myLayout" android:layout_width="fill_parent" android:layout_height="fill_parent" android:enabled="true" android:layout_centerHorizontal="true" android:clickable="true" />

    </RelativeLayout>

Please try it out, if you require it.
