und die Ausnahme in dieser Zeile

 convertView = mInflater.inflate(R.layout.drawer_list_item, null); 

in dieser Klasse: [NavDrawerListAdapter.java]

package emy.dt4it.healthytips; 
import java.util.ArrayList; 

import android.app.Activity; 
import android.content.Context; 
import android.graphics.Typeface; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.BaseAdapter; 
import android.widget.ImageView; 
import android.widget.TextView; 

public class NavDrawerListAdapter extends BaseAdapter { 

private Context context; 
private ArrayList<NavDrawerItem> navDrawerItems; 

public NavDrawerListAdapter(Context context, ArrayList<NavDrawerItem> navDrawerItems){ 
    this.context = context; 
    this.navDrawerItems = navDrawerItems; 
} 

@Override 
public int getCount() { 
    return navDrawerItems.size(); 
} 

@Override 
public Object getItem(int position) {  
    return navDrawerItems.get(position); 
} 

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

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    if (convertView == null) { 
     LayoutInflater mInflater = (LayoutInflater) 
       context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE); 
     convertView = mInflater.inflate(R.layout.drawer_list_item, null); 
    } 

    ImageView imgIcon = (ImageView) convertView.findViewById(R.id.icon); 
    TextView txtTitle = (TextView) convertView.findViewById(R.id.title); 
    TextView txtCount = (TextView) convertView.findViewById(R.id.counter); 

    Typeface tf = Typeface.createFromAsset(context.getAssets(), "fonts/bauhausm_0.ttf"); 
    txtTitle.setTypeface(tf); 
    txtCount.setTypeface(tf); 

    imgIcon.setImageResource(navDrawerItems.get(position).getIcon());   
    txtTitle.setText(navDrawerItems.get(position).getTitle()); 

    // displaying count 
    // check whether it set visible or not 
    if(navDrawerItems.get(position).getCounterVisibility()){ 
     txtCount.setText(navDrawerItems.get(position).getCount()); 
    }else{ 
     // hide the counter view 
     txtCount.setVisibility(View.GONE); 
    } 

    return convertView; 
} 

} 

und das Layout [drawer_list_item]

<RelativeLayout android:layout_width="match_parent" 
    android:layout_height="48dp" 
    android:background="@drawable/list_selector"> 
    <ImageView android:id="@+id/icon" 
     android:layout_width="25dp" 
     android:layout_height="wrap_content" 
     android:layout_alignParentLeft="true" 
     android:layout_marginLeft="12dp" 
     android:layout_marginRight="12dp" 
     android:src="@drawable/menu_tip" 
     android:layout_centerVertical="true"/> 
    <TextView android:id="@+id/title" 
     android:layout_width="wrap_content" 
     android:layout_height="match_parent" 
     android:layout_toRightOf="@id/icon" 
     android:minHeight="?android:attr/listPreferredItemHeightSmall" 
     android:textAppearance="?android:attr/textAppearanceListItemSmall" 
     android:textColor="#4f4f4f" 
     android:textSize="18sp" 
     android:text="try" 
     android:gravity="center_vertical" 
     android:paddingRight="40dp"/> 
    <TextView android:id="@+id/counter" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignParentRight="true" 
     android:layout_centerVertical="true" 
     android:text="2" 
     android:layout_marginRight="8dp" 
     android:textColor="#959595"/> 
</RelativeLayout> 

Hoffnung jemand könnte mir helfen. Danke im Voraus.

Answer 1

Fehler in XML
Überprüfen Sie, ob Sie sich in Zeile 17 Ihrer Einreichung befinden.

android:attr/textAppearanceListItemSmall
, wenn der Fehler hier api Pegeländerung

im Manifest ist

Answer 2

Die innerste Ausnahme bedeutet, dass einer Ihrer Textviews haben ungültige Dimensionen erklärt. Überprüfen Sie die von Ihnen verwendete SDK-Ebene, da android:attr/listPreferredItemHeightSmall und android:attr/textAppearanceListItemSmall ab API-Stufe 14 verfügbar sind.

(hinzugefügt von meinem Kommentar, der das Problem behoben)

Answer 3

ich den gleichen Fehler auf der gleichen Linie gefunden, und es dauerte zwei Tage, um herauszufinden, was der Fehler war.

Der Fehler war einfach, weil ich versuchte, eine zu verwenden: android:background

Statt: app:srcCompat

in einer SVG-Datei.

In Ihrem Fall

<ImageView android:id="@+id/icon" 
     android:layout_width="25dp" 
     android:layout_height="wrap_content" 
     android:layout_alignParentLeft="true" 
     android:layout_marginLeft="12dp" 
     android:layout_marginRight="12dp" 
     android:src="@drawable/menu_tip" <-- the error is here 
     android:layout_centerVertical="true"/> 

der Fehler erscheint auch, wenn Sie verwenden: android:src=" "

Ich hoffe, das hilft.
