如何在Android的页面中显示长字符串？

Question

I have a large String from the database. I showed it in the TextView with scrolling.

This is a totally boring method to show large text though; I want to show data in pages.

There are multiple questions similar to this one, but I am not able to find any solutions from them; they are incomplete and off track.

Challenges

1. How to count number of lines that fit to screen?
2. How to split string in sub parts so that each substring fits to a page?

Answer 1

I think this should solve the problem, 1. it will split the large string 2. display on view as you want

So if u dont want to use Scroll View then well i tried something and i hope it helps

Following i done 1. inflate required views into parent view

2. set large text into Textview

3. Check if other text views are within the (visible) screen or not

4. update appropriately

Main Activity class

public class MainActivity extends Activity {

 private TextView text1, text2; private Context context; private LinearLayout layout; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); context = getLayoutInflater().getContext(); layout = (LinearLayout) findViewById(R.id.parentLayout); setTextViews(); // checkViewAndUpdate(); layout.getViewTreeObserver().addOnGlobalLayoutListener( new ViewTreeObserver.OnGlobalLayoutListener() { @Override public void onGlobalLayout() { checkViewAndUpdate(); } }); } private void checkViewAndUpdate() { Rect rect = new Rect(); layout.getHitRect(rect); if (text1.getLocalVisibleRect(rect)) { Toast.makeText(context, "visible", Toast.LENGTH_LONG).show(); } else { // update if not visible decreasing the view text size Toast.makeText(context, "Not visible", Toast.LENGTH_LONG).show(); } if (text2.getLocalVisibleRect(rect)) { Toast.makeText(context, "visible", Toast.LENGTH_LONG).show(); } else { // update if not visible decreasing the view text size Toast.makeText(context, "Not visible", Toast.LENGTH_LONG).show(); } } private void setTextViews() { text1 = new TextView(context); text2 = new TextView(context); text1.setText("your link seems to work. where/when do u trying to call getXXXVisibleRect()? if u do it at onCreate your link seems to work. where/when do u trying to call getXXXVisibleRect()? if u do it at onCreate your link seems to work. where/when do u trying to call getXXXVisibleRect()? if u do it at onCreateyour link seems to work. where/when do u trying to call getXXXVisibleRect()? if u do it at onCreate "); text2.setText("text2"); text1.setTextSize(30); text2.setTextSize(30); // layout.removeAllViews(); layout.addView(text1); layout.addView(text2); }
