Hi, ich verscuhe eine app mit einem TabHost zumachen wenn ich allerdings einen Tab hinzufügen will stürzt das ganze ab.

MainActivity.jaba
1package com.example.emu;
2
3import android.os.Bundle;
4import android.app.Activity;
5import android.view.Menu;
6import android.widget.*;
7import android.content.Intent;
8public class MainActivity extends Activity {
9
10 @Override
11 public void onCreate(Bundle savedInstanceState) {
12 super.onCreate(savedInstanceState);
13 setContentView(R.layout.activity_main);
14 TabHost t = (TabHost)findViewById(android.R.id.tabhost);
15 t.setup();
16 TabHost.TabSpec s = t.newTabSpec("Tab1");
17 s.setContent(new Intent(this,Do.class));
18 t.addTab(s);
19 }
20
21 @Override
22 public boolean onCreateOptionsMenu(Menu menu) {
23 getMenuInflater().inflate(R.menu.activity_main, menu);
24 return true;
25 }
26}

Do ist eine Activity an der ich nichts verändert habe weis einer wo das Problem liegt?

Hmm, siehst so aus als wäre da etwas in der XML Datei falsch. Clean mal das Projekt und schau Dir das mal genauer an.

Caused by: android.view.InflateException: Binary XML file line #12: Error inflating class activity

at android.app.Activity.setContentView(Activity.java:1647) at com.example.emu.MainActivity.onCreate(MainActivity.java:13)
