Line break without increasing text length

I can break the string using the following code:

String str1 = "TEST1"; // length = 5 String str2 = "TEST2"; // length = 5 TextView textView = (TextView)findViewById( R.id.text_view ); textView.setText(str1 + '\n' + str2);

But the final length of the text is 11.

Question:

Is there any special character or method that will allow me to achieve the same result inside my TextView without increasing the length of the text?

What I'm trying to achieve:

I have a data format that is stored in JSON. He looks like

 [{type: line, params: {line params}}, {type: text, params: {text params}, ...]

  • There is always a line at the beginning

  • Each paragraph begins with a line (therefore, it acts as a line separator, which is stored at the beginning of the line, not at the end)

  • The size of each line is 1, that is, each line is considered a single character

  • Each paragraph ends with the text of the last character (not '\ n')

  • There are some line parameters (e.g. BulletList, Numeric list, Paragraph)

I need a strict comparison between my TextView and the source data, i.e. for each cursor position in my TextView I need to calculate how many characters precede the original data.

On your question, my answer will be no. But you can make your own TextView and change how it calculates the length of the text, for example, ignoring "/ n" when counting the length.

Take two text elements and add them below the other. Then you will not find a problem with the length.

  like : <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="TextView1" /> <TextView android:id="@+id/textView2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/textView1" android:text="TextView2" /> </RelativeLayout>

 String str1 = "TEST1"; String str2 = "TEST2"; TextView text=(TextView)vi.findViewById(R.id.text); text.setText(str1); text.append(Html.fromHtml(< br>)); text.append(str2);

Hope it works :)

Well, there is a difficult way

  String str1 = "TEST1"; // length = 5 String str2 = "TEST2"; // length = 5 textView = (TextView)findViewById( R.id.textView1 ); textView.setWidth(120); textView.setTextSize(20); textView.setText(str1 + str2); //textView.getText().toString().length() length = 10

in xml

 <TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:text="TextView" />
