以编程方式添加的相对布局将不会显示

我正在尝试以编程方式添加某个Relative Layout xml。它由ImageView,EditText和TextView组成。问题似乎是我在从另一个活动返回后尝试在“onActivityResult”方法上执行此操作。当我在其他地方工作时,它可以工作,我想要创建的布局正确显示(例如我尝试成功“onCreate”并按下按钮),但如果在“onActivityResult”内部不起作用。我需要它在那里。

在任何一种情况下都能成功输出打印件,没有错误或崩溃,但布局不会显示。任何建议都表示赞赏。

这是我要创建的xml文件:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" android:layout_height="260dip">

    <ImageView
        android:id="@+id/damagePicture"
        android:layout_width="match_parent"
        android:layout_height="210dip"
        android:scaleType="centerCrop"
        android:layout_marginTop="10dip"
        android:layout_marginLeft="10dip"
        android:layout_marginRight="10dip"
        android:src="@drawable/nocar"/>

    <EditText
        android:id="@+id/orderTextfield"
        android:layout_height="40dip"
        android:layout_width="match_parent"
        android:gravity="left|center"
        android:layout_marginLeft="10dip"
        android:layout_marginRight="45dip"
        android:hint="Enter damage description"
        android:textSize="14sp"
        android:layout_alignParentLeft="true"
        android:textColor="@color/black"
        android:textColorHint="@color/gray_vin_search_text"
        android:background="@null"
        android:singleLine="true"
        android:editable="true"
        android:layout_below="@+id/damagePicture"/>

    <TextView
        android:id="@+id/removePicture"
        android:layout_width="40dip"
        android:layout_height="40dip"
        android:text="@string/discardPicture"
        android:gravity="center|center"
        android:textColor="@color/black"
        android:textSize="24sp"
        android:layout_alignParentRight="true"
        android:layout_alignParentBottom="true"
        android:clickable="true"
        android:onClick="removePicture"/>

    <View
        android:id="@+id/bottomLine"
        android:layout_width="match_parent"
        android:layout_height="1dip"
        android:layout_alignParentBottom="true"
        android:background="@color/gray_for_line"></View>

</RelativeLayout>

以下是代码的相关部分:

public void addResultingDamagePicture(String pathToFile) {
        System.out.println("ADD RESULTING DAMAGE PICTURE");
        LayoutInflater layoutInflater = (LayoutInflater) this.getSystemService(this.LAYOUT_INFLATER_SERVICE);
        View damagePictureSet = layoutInflater.from(this).inflate(R.layout.damage_picture_set, picturesCell, false);
        ((TextView) damagePictureSet.findViewById(R.id.removePicture)).setTypeface(fontAwesome);
        TextView remove = (TextView)damagePictureSet.findViewById(R.id.removePicture);
        remove.setTypeface(fontAwesome);
        File imgFile = new  File(pathToFile);
        if(imgFile.exists()) {
            System.out.println("ADD RESULTING DAMAGE PICTURE - FILE OK");
            BitmapFactory.Options opt = new BitmapFactory.Options();
            opt.inSampleSize = 4;
            final Bitmap thebmp = BitmapFactory.decodeFile(imgFile.getAbsolutePath(), opt);
            ((ImageView) damagePictureSet.findViewById(R.id.damagePicture)).setImageBitmap(thebmp);
            picturesCell.addView(damagePictureSet);
        } else {
            System.out.println("ADD RESULTING DAMAGE PICTURE - NO FILE EXISTS!!!");
        }
        return;
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == SHOOT_DAMAGE_PICTURE && resultCode == RESULT_OK) {
            final String encodedPicture = data.getStringExtra("PATH_TO_PICTURE");
            System.out.println("PICTURE RESULT = " + encodedPicture);
            addResultingDamagePicture(encodedPicture);
        } else {
            System.out.println("ON ACTIVITY RESULT = NOT OK");
            return;
        }
    }

在某些情况下,可以在onCreate方法之后调用onActivityResult方法。在这种情况下,再次调用setContentView方法,再次呈现初始布局。您可能需要设置一些标记,或者根据Activity更新数据,以便根据标记/数据重新创建View
