我得到错误

Unable to start activity ComponentInfo{de.androidbuch.activiti/de.androidbuch.activiti.task.Activity}: android.view.InflateException: Binary XML file line #9: Error inflating class fragment

我在 Android android 中阅读了错误膨胀类片段， 错误膨胀类片段 ，但它对我不起作用

 package com.example.fragments;

 import android.os.Bundle;
 import android.support.v4.app.FragmentActivity;
 import android.util.Log;

 public class MainActivity extends FragmentActivity {
String LOG_TAG = "myLogs";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);
    Log.d(LOG_TAG, "MainActivity onCreate");
}

protected void onStart() {
    super.onStart();
    Log.d(LOG_TAG, "MainActivity onStart");
}

protected void onResume() {
    super.onResume();
    Log.d(LOG_TAG, "MainActivity onResume");
}

protected void onPause() {
    super.onPause();
    Log.d(LOG_TAG, "MainActivity onPause");
}

protected void onStop() {
    super.onStop();
    Log.d(LOG_TAG, "MainActivity onStop");
}

protected void onDestroy() {
    super.onDestroy();
    Log.d(LOG_TAG, "MainActivity onDestroy");
}

}

当你使用

android:name="ru.startandroid.develop.p1041fragmentlifecycle.Fragment1"

您需要提供包名称。从您的 frag1.java 文件中，包名称是package com.example.fragments;所以对于您想要使用的 xml 文件

android:name="com.example.fragments.Frag1"

或简称：

android:name=".Frag1"
