在下面的代码中，我无法获得纬度，经度和海拔高度的预期值，但是却获得了文本值的名称和详细信息。我不知道为什么会这样。下面是我的适配器打算类...

newlist.add(databasemodelist.get(i));
}
}
@NonNull
@Override
public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
return new SaveListAdapter.ViewHolder(LayoutInflater.from(parent.getContext()).inflate(R.layout.recycle_view_icon, parent, false));
}
@Override

final DatabseMode databseMode = newlist.get(position);
holder.name.setText(databseMode.getname());

DatabseMode databseMode = newlist.get(position);
Intent intent=new Intent(context.getApplicationContext(),Edit.class);
intent.putExtra("id",databseMode.getid());

public TextView name;
public TextView detail;
public ViewHolder(View itemView) {

detail = itemView.findViewById(R.id.textview00);
}
}}
我打算发送详细信息，但是我无法仅获取纬度，经度和海拔，但是为什么我可以获取文本名称和详细信息？
package com.onebook.locationsaver;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ImageButton;
import android.widget.TextView;
public class Edit extends Activity {
private TextView msavelatitude,msavelongitude,msavealtitude;
private EditText name,detail;
private ImageButton save,back;
private Button btn;
private DatabaseHelper databaseHelper;
Context context;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.edit);
msavelatitude=findViewById(R.id.meditlatitude);
msavelongitude=findViewById(R.id.meditlongitude);
msavealtitude=findViewById(R.id.meditaltitude);
save=findViewById(R.id.meditsave);
back=findViewById(R.id.meditcrossss);
name=findViewById(R.id.meditname);
detail=findViewById(R.id.meditdetail);
btn=findViewById(R.id.meditblank);
databaseHelper=new DatabaseHelper(this);
Intent intend = getIntent();
Bundle bundle=intend.getExtras();
String latitude= (String) bundle.get("latitude");
String longitude= (String) bundle.get("longitude");
String altitude= (String) bundle.get("altitude");
String mname=bundle.getString("name");
String mdetail=bundle.getString("detail");
msavelatitude.setText((String) bundle.get("latitude"));
msavelongitude.setText((String) bundle.get("longitude"));
msavealtitude.setText((String) bundle.get("altitude"));
name.setText(mname);
detail.setText(mdetail);
}
}
然后我的logcat错误类似于以下类型的“ 无法获取内存消耗信息：-1 ” 和“ memtrack模块”
