Android Display Long Long Text

I'm working on this case for several days. I have a file with 20 thousands lines text to be displayed in an activity. I use a TextView in a ScrollView to display the text. Everythi

Solution 1:

For that task I've developed a library (class) called LongTextView: https://github.com/metalurgus/LongTextView

Usage:

<com.metalurgus.longtextview.LongTextView 
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:gravity="left|top"
    app:maxLinesPerItem="2"
    app:text="@string/long_text"
    app:textColor="#ff0000"
    app:textSize="5dp" />

How it works:

It splits whole text into parts, and shows it as a ListView items using recycling, and therefore - with no UI lag and OOM due to enormous TextView

Solution 2:

You need to set the hardware acceleration as false in your manifest.xml file as mentioned here - https://stackoverflow.com/a/12118798/1649353

Or try like this

Viewscroll= layout.findViewById(R.id.scrollView1);
scroll.setLayerType(View.LAYER_TYPE_SOFTWARE, null);

Solution 3:

Try this:

TextViewtxtDetails= (TextView) findViewById(R.id.txtDetails);
txtDetails.setText("Your Text");
txtDetails.setMovementMethod(newScrollingMovementMethod());
