Erweitern Textansicht Höhe in android benutzerdefinierte Listview

Question

Ich habe eine benutzerdefinierte Listenansicht mit Textansicht. Wenn auf die Textansicht geklickt wird, muss die Zeilenhöhe basierend auf dem verfügbaren Text erhöht werden. Zum Beispiel, wenn holder.asr_tv_Content wird die aktuelle Zeile gedrückt, wo er gedrückt wird, hat zusammen mit anderen Kontrollen Höhe

public class StudentRemarksAdapter extends BaseAdapter { 

     Context _Context = null; 
     ArrayList<String> _as_Day; 
     ArrayList<String> _as_Month; 
     ArrayList<String> _as_Year; 
     ArrayList<String> _as_Heading; 
     ArrayList<String> _as_Content; 
     ArrayList<String> _as_Values; 
     LayoutInflater inflater = null; 

     public StudentRemarksAdapter(Context a_Context, 
       ArrayList<String> as_Day, ArrayList<String> as_Month, 
       ArrayList<String> as_Year, ArrayList<String> as_Heading, 
       ArrayList<String> as_Content, ArrayList<String> as_Values) { 
      // TODO Auto-generated constructor stub 
      this._Context = a_Context; 

      this._as_Day = as_Day; 
      this._as_Month = as_Month; 
      this._as_Year = as_Year; 
      this._as_Heading = as_Heading; 
      this._as_Content = as_Content; 
      this._as_Values = as_Values; 
      inflater = (LayoutInflater) _Context 
        .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

     } 

     @Override 
     public int getCount() { 
      // TODO Auto-generated method stub 
      return _as_Day.size(); 
     } 

     @Override 
     public Object getItem(int position) { 
      // TODO Auto-generated method stub 
      return position; 
     } 

     @Override 
     public long getItemId(int position) { 
      // TODO Auto-generated method stub 
      return position; 
     } 

     public class Holder { 
      RelativeLayout asr_rl_background; 
      TextView asr_tv_Day, asr_tv_Month, asr_tv_Year, asr_tv_Heading, 
        asr_tv_Content; 

     } 

     @Override 
     public View getView(final int position, View convertView, 
       ViewGroup parent) { 
      // TODO Auto-generated method stub 
      Holder holder = new Holder(); 
      if (convertView == null) { 
       holder = new Holder(); 

       convertView = inflater.inflate(R.layout.adapter_studentremarks, 
         null); 

       holder.asr_rl_background = (RelativeLayout) convertView 
         .findViewById(R.id.asr_rl_background); 

       holder.asr_tv_Day = (TextView) convertView 
         .findViewById(R.id.asr_tv_Day); 
       setControlsStyle 
         .SetCustomTextViewStyleForContent(holder.asr_tv_Day); 

       holder.asr_tv_Month = (TextView) convertView 
         .findViewById(R.id.asr_tv_Month); 
       setControlsStyle 
         .SetCustomTextViewStyleForContent(holder.asr_tv_Month); 

       holder.asr_tv_Year = (TextView) convertView 
         .findViewById(R.id.asr_tv_Year); 
       setControlsStyle 
         .SetCustomTextViewStyleForContent(holder.asr_tv_Year); 

       holder.asr_tv_Heading = (TextView) convertView 
         .findViewById(R.id.asr_tv_Heading); 
       setControlsStyle 
         .SetCustomTextViewStyleForContentWithBlackText(holder.asr_tv_Heading); 

       holder.asr_tv_Heading.setTextSize(18); 
       holder.asr_tv_Heading.setGravity(Gravity.CENTER | Gravity.LEFT); 

       holder.asr_tv_Content = (TextView) convertView 
         .findViewById(R.id.asr_tv_Content); 
       setControlsStyle 
         .SetCustomTextViewStyleForContentWithBlackText(holder.asr_tv_Content); 
       holder.asr_tv_Month.setTextSize(14); 
       holder.asr_tv_Year.setTextSize(14); 

       holder.asr_tv_Content.setGravity(Gravity.TOP | Gravity.LEFT); 
       convertView.setTag(holder); 
      } 

      else { 
       holder = (Holder) convertView.getTag(); 
      } 

      holder.asr_tv_Day.setText(_as_Day.get(position)); 
      holder.asr_tv_Day.setTextSize(26); 

      holder.asr_tv_Month.setText(_as_Month.get(position)); 

      holder.asr_tv_Year.setText(_as_Year.get(position)); 

      holder.asr_tv_Heading.setText(_as_Heading.get(position)); 
      holder.asr_tv_Content.setText(_as_Content.get(position)); 



      if (_as_Values.get(position).equals(
        _Context.getResources() 
          .getStringArray(R.array.as_mode_Text)[0])) { 
       holder.asr_rl_background.setBackgroundColor(_Context 
         .getResources().getColor(
           R.color.asr_tv_positiveicon_bgcolor)); 
      } else { 
       holder.asr_rl_background.setBackgroundColor(_Context 
         .getResources().getColor(
           R.color.asr_tv_negativeicon_bgcolor)); 
      } 

      return convertView; 
     } 
    } 

Answer 1

Stellen die Sicht auf Höhe WRAP_CONTENT (und tut dasselbe für ihre Vorfahren)

Wenn erhöht Sie zeigen den Text standardmäßig zeigen einen kleinen Teil davon

private static final int MAX_LEN = 22; //choose this yourself 

if (text.length() > MAX_LEN) { 
    textView.setText(text.substring(0, MAX_LEN) + "..."); 
} else { 
    textView.setText(text); 
} 

Dann onClick, aktualisieren Sie wieder mit dem vollen Wert

textView.setText(text);
