具有layout.xml的android旋转器文本大小不起作用

Question

I have this layout

spinnertipocombustible.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal">
    <TextView
        android:id="@+id/textview"
        android:layout_height="30dip"
        android:layout_width="wrap_content"
        android:textSize="50dip"
        android:textColor="#ccddaa"
        />
</LinearLayout>

and in dialogfragment I have this code

listado=DM.RegresaTiposCombustible();
adapter= new TiposCombustibleAdapter(getActivity(),R.layout.spinnertipocombustible,listado);
adapter.setDropDownViewResource(R.layout.spinnertipocombustible);
spinner.setAdapter(adapter);

in next picture you can see the text size which not change if I change this line in spinnertipocombustible.xml

android:textSize="50dip"

this is my adapter..

public class TiposCombustibleAdapter extends ArrayAdapter<TipoCombustible>{

    private Context context;

    private List<TipoCombustible> tipoCombustibles;

    public TiposCombustibleAdapter(Context context, int textViewResourceId, List<TipoCombustible> tiposCombustible){

        super(context,textViewResourceId,tiposCombustible);
        this.context=context;
        this.tipoCombustibles=tiposCombustible;

    }

    public  int getCount(){

        return  tipoCombustibles.size();
    }

    public TipoCombustible getItem(int position){
        return  tipoCombustibles.get(position);
    }

    public long getItemId(int position){
        return  position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // I created a dynamic TextView here, but you can reference your own  custom layout for each spinner item
        TextView label = new TextView(context);
        label.setTextColor(Color.BLACK);
        // Then you can get the current item using the values array (Users array) and the current position
        // You can NOW reference each method you has created in your bean object (User class)
        label.setText(tipoCombustibles.get(position).getDescripcion());

        // And finally return your dynamic (or custom) view for each spinner item
        return label;
    }

    @Override
    public View getDropDownView(int position, View convertView,
                                ViewGroup parent) {
        TextView label = new TextView(context);
        label.setTextColor(Color.BLACK);
        label.setText(tipoCombustibles.get(position).getDescripcion());

        return label;
    }


}

Answer 1

Try using 50sp or 50dp instead of 50dip . You might also want to try to change layout_height to wrap_content instead of a fixed value.

Answer 2

Take a look here . Available units for android:textSize are:

Available units are: px (pixels), dp (density-independent pixels), sp (scaled pixels based on preferred font size), in (inches), mm (millimeters).

So, instead of android:textSize="50dip" , use any acceptable unit (eg, dp or sp).

Answer 3

Instead of android:textSize="50dip" , use any acceptable unit like dp and sp .

Example

android:textSize="50dp"
android:textSize="50sp"

Answer 4

Dont use LinearLayout. just remove that layout and increase your textsize. It will work.

Answer 5

try this code...... Remove linearlayout from your textview and use it.

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/textview"
    android:layout_height="wrap_content"
    android:layout_width="wrap_content"
    android:textSize="50dp"
    android:textColor="#ccddaa"
    />
