扩展 AppCompActivity 给出未捕获的异常

Question

在我的 MainActivity 中，当我按下一个按钮时，我必须打开另一个扩展 AppCompacActivity 的 activity。问题是我的应用程序因为未处理的异常而崩溃。这是代码

主程序代码：

Button NextButton = (Button)findViewById(R.id.next_button);
    NextButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(getApplicationContext(), GeofenceMainActivity.class);
            startActivity(intent);
        }
    });

GeofenceMainActivity 代码：

package com.clb.apokalos.todolistas;

import android.app.PendingIntent;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.common.api.GoogleApiClient.ConnectionCallbacks;
import com.google.android.gms.common.api.GoogleApiClient.OnConnectionFailedListener;
import com.google.android.gms.common.api.ResultCallback;
import com.google.android.gms.common.api.Status;
import com.google.android.gms.location.Geofence;
import com.google.android.gms.location.GeofencingRequest;
import com.google.android.gms.location.LocationServices;
import com.google.android.gms.location.GeofencingApi;
import com.google.android.gms.maps.model.LatLng;

import java.util.ArrayList;
import java.util.Map;

/**
 * Demonstrates how to create and remove geofences using the GeofencingApi. Uses an IntentService
 * to monitor geofence transitions and creates notifications whenever a device enters or exits
 * a geofence.
 *
 * This sample requires a device's Location settings to be turned on. It also requires
 * the ACCESS_FINE_LOCATION permission, as specified in AndroidManifest.xml.
 *
 * Note that this Activity implements ResultCallback<Status>, requiring that
 * {@code onResult} must be defined. The {@code onResult} runs when the result of calling
 * {@link GeofencingApi#addGeofences(GoogleApiClient, GeofencingRequest, PendingIntent)}  addGeofences()} or
 * {@link com.google.android.gms.location.GeofencingApi#removeGeofences(GoogleApiClient, java.util.List)}  removeGeofences()}
 * becomes available.
 */
public class GeofenceMainActivity extends AppCompatActivity implements
        ConnectionCallbacks, OnConnectionFailedListener, ResultCallback<Status> {

    //variables here.

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

    protected synchronized void buildGoogleApiClient() {...}

    @Override
    protected void onStart() {...}

    @Override
    protected void onStop() {...}

    @Override
    public void onConnected(Bundle connectionHint) {...}

    @Override
    public void onConnectionFailed(ConnectionResult result) {...}

    @Override
    public void onConnectionSuspended(int cause) {...}

    private GeofencingRequest getGeofencingRequest() {...}

    public void addGeofencesButtonHandler(View view) {...}

    public void removeGeofencesButtonHandler(View view) {...}

    private void logSecurityException(SecurityException securityException) {...}

    public void onResult(Status status) {...}

    private PendingIntent getGeofencePendingIntent() {...}

    public void populateGeofenceList() {...}

    private void setButtonsEnabledState() {...}
}

此代码已被修改，因为在它的原始实现中，它扩展了 ActionBarActivity（现已弃用），因此我修改了代码，将 ActionBarActivity 替换为 AppCompatActivity。

错误代码只是：threadid=1: thread exiting with uncaught exception (group=0x41da6438)

你能帮帮我吗？尝试块似乎无法帮助我找到解决方案。

编辑：我有堆栈跟踪

尝试在您的清单中添加此主题：

android:theme="@style/Theme.AppCompat" >

在 activity 标签中

 <activity
        android:name=".GeofenceMainActivity"
        android:label="@string/app_name"
        android:theme="@style/Theme.AppCompat" />
