Question

我有一个活动MarkerDetailedActivity，它应该显示有关标记的所有信息（照片/日期/作者/描述/标题）。问题是代码认为mDateTextView是mDescriptionTextView。但是在xml文件中，所有内容都写得正确。

我的xml设计屏幕

MarkerDetailedActivity.class

public class MarkerDetailsActivity extends AppCompatActivity {
private static final String EXTRA_MARKER = "marker";

public static Intent getStartIntent(Context context, Marker marker) {
    Intent startIntent = new Intent(context, MarkerDetailsActivity.class);
    startIntent.putExtra(EXTRA_MARKER, marker);
    return startIntent;
}


ImageView mImageView;

TextView mNameTextView;

TextView mAuthorTextView;

TextView mDateTextView;

TextView mDescriptionTextView;

Marker mMarker;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_details_marker);
    mMarker = getIntent().getParcelableExtra(EXTRA_MARKER);


    Toolbar toolbar = findViewById(R.id.toolbar);
    toolbar.setTitle(mMarker.getName());
    toolbar.setNavigationOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            onBackPressed();
        }
    });


    mImageView = findViewById(R.id.image_view);
    mDateTextView = findViewById(R.id.text_view_date);
    mAuthorTextView = findViewById(R.id.text_view_author);
    mDescriptionTextView = findViewById(R.id.text_view_description);
    bindMarker(mMarker);
}

private void bindMarker(Marker marker) {
    Picasso.with(mImageView.getContext())
            .load(marker.getImage().getUrl())
            .into(mImageView);
    mAuthorTextView.setText(marker.getAuthor());
    mDescriptionTextView.setText(marker.getDescription());
    mDateTextView.setText(marker.getDate());
  }
}

这是我的xml文件 activity_details_marker.xml

如何解决这个问题？

Answer 1

检查您的模型类标记。您将访问日期方法设为：

String date;
String description;
public String getDate(){
return description;
}

或者你可能在日期方法中设置描述

String date;
String description;
public void setDate(String s){
description = s;
}

反之亦然

最好的方法是不要在课堂上右键单击任何方法并选择getter和setter。

Answer 2

检查您的标记实例，并将其作为包裹传递到您的位置。您必须在date属性中传递描述。确保在标记对象属性中传递正确的值。
