Question

致命的例外：主要处理：org.example.easyparking，PID：6371 java.lang.RuntimeException：无法启动活动 ComponentInfo {org.example.easyparking / org.example.easyparking.MapActivity}： android.view.InflateException：二进制XML文件行＃0：二进制XML 文件行＃0：错误膨胀类片段

这是我的mapactivity

    package org.example.easyparking;
    import android.app.Dialog;
    import android.support.v7.app.AppCompatActivity;
    import android.os.Bundle;
    import android.widget.Toast;


    import com.google.android.gms.common.ConnectionResult;
    import com.google.android.gms.common.GoogleApiAvailability;
    import com.google.android.gms.maps.GoogleMap;
    import com.google.android.gms.maps.MapFragment;
    import com.google.android.gms.maps.OnMapReadyCallback;

    public class MapActivity extends AppCompatActivity implements 
    OnMapReadyCallback {

    GoogleMap mGoogleMap;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_map);
    if(googleServicesAvailable()){

        setContentView(R.layout.activity_map);
        initMap();
    }else{
        //No Google Map Layout
    }
}

private void initMap() {
    MapFragment mapFragment = (MapFragment) getFragmentManager().
            findFragmentById(R.id.mapFragment);
    mapFragment.getMapAsync(this);
}

public boolean googleServicesAvailable(){
    GoogleApiAvailability api = GoogleApiAvailability.getInstance();
    int isAvailable = api.isGooglePlayServicesAvailable(this);
    if(isAvailable == ConnectionResult.SUCCESS){
        return true;
    }else if (api.isUserResolvableError(isAvailable)){
        Dialog dialog = api.getErrorDialog(this, isAvailable, 0);
        dialog.show();
    }else{
        Toast.makeText(this, "Can't connect", Toast.LENGTH_LONG)
                .show();
    }
    return false;
}

@Override
public void onMapReady(GoogleMap googleMap) {
    mGoogleMap = googleMap;
}
}

这是显而易见的

这是第一项活动

    package org.example.easyparking;
    import android.content.Intent;
    import android.support.v7.app.AppCompatActivity;
    import android.os.Bundle;
    import android.view.View;
    import android.widget.Button;
    import android.widget.Toast;

public class FirstActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_first);
    Button button = (Button) this.findViewById(R.id.button);
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            Toast.makeText(getApplicationContext(),
                    "Make sure that your location is turned on",
                    Toast.LENGTH_LONG).show();

            Intent newacti = new Intent(FirstActivity.this, MapActivity.class);
            startActivity(newacti);
        }
    });

    Button button_parking_owner = (Button) this.findViewById(R.id.button2);
    button_parking_owner.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent newacti = new Intent(FirstActivity.this, SecondActivity.class);
            startActivity(newacti);
        }
    });
}
}

Answer 1

在MapActivity中，您正在检查googleServicesAvailable()是否可用，如果没有，则表示您未提供要呈现的默认内容

if(googleServicesAvailable()){

        setContentView(R.layout.activity_map);
        initMap();
    }else{
        //No Google Map Layout
    }

尝试创建一个基本布局来呈现类似 No Google Map 的内容即你应该有类似

的东西

if(googleServicesAvailable()){

        setContentView(R.layout.activity_map);
        initMap();
    }else{
        //No Google Map Layout
        setContentView(R.layout.no_activity_map);
    }

然后创建no_activity_map布局

为什么我在logcat（Android）中收到此错误？
