Simple solution for your entire pojo fields:

for (Post post : posts) {
 String content = "";
 content += "ID: " + post.getId() + "\n";
 content += "User ID: " + post.getUserId() + "\n";
 content += "Title: " + post.getTitle() + "\n";
 content += "Text: " + post.getText() + "\n\n";

 textViewResult.append(content);         
  }
 }

For kotlin :

   posts.forEach {post->
        var content = ""
        content += "ID: " +  post.id + "\n"
        content += "User ID: " + post.userId + "\n"
        content += "Title: " + post.title + "\n"
        content += "Text: " + post.text + "\n\n"
      textViewResult.append(content)
    }

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main3);
    Bundle bundle = getIntent().getExtras();
    assert bundle != null;
    ArrayList<String> expTit = bundle.getStringArrayList("expTit");
    ArrayList<Integer> expAmt =bundle.getIntegerArrayList("expAmt");
    TextView t= findViewById(R.id.textView2);
    TextView t2= findViewById(R.id.textView3);
    StringBuilder builder = new StringBuilder();
    if (expTit == null) throw new AssertionError();
    String text="";
    for (String details : expTit) {
        text = text + details + "\n";
    }
    t.setText(text);
}

Use a StringBuilder to make your array 1 String and append linebreaks in between the individual Strings like this: 

StringBuilder builder = new StringBuilder();
for (String details : list2) {
   builder.append(details + "\n");
}

custName.setText(builder.toString());

You can combine your details as a single string and separate with a newline character:

String text="";
for (String details : list2) {
    text = text + details + "\n";
}
custName.setText(details);

Hi you can set the Max lines in Text View 

  <TextView
android:id="@+id/address1"
android:gravity="left"
android:layout_height="fill_parent"
android:layout_width="wrap_content"
android:maxLines="4"
android:lines="4"
android:text="Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod   tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat."></TextView>

Change your layout_width from wrap_content to particular size like below:

<TextView
            android:id="@+id/kbpViewTvCustNm"
            android:layout_width="80dp"
            android:layout_height="wrap_content"
            android:layout_marginBottom="4dp"
            android:layout_marginLeft="8dp"
            android:lines="4"
            android:textIsSelectable="false" />
