在表行android

Question

我有一个小问题。在我的表格行中我想添加一个FacebookProfilePictureView，除了添加一个简单的ImageView之外，这会给我带来一些错误。我附上的图片显示了我收到的输出。

序列号右侧的白框是始终设置profilepicview的位置。另外，在xml中我将大小设置为50,50（宽度，高度），但在java中它变得混乱。我的代码如下。

XML代码：

<TableLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_below="@id/view_below_linear_layout_three_team_spuck"
    android:id="@+id/the_maintable_team_spuck"
    >

    <TableRow
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/the_maintable_row_team_spuck">

        <com.facebook.login.widget.ProfilePictureView
            android:id="@+id/profile_pic_view_team_spuck"
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:visibility="gone"
            android:layout_alignParentTop="true"
            android:layout_alignParentLeft="true"
            android:layout_alignParentStart="true" />

    </TableRow>
</TableLayout>

Java代码：

the_normal_image_view = new ImageView(view.getContext());  // this is the normal image view, no issues when adding this in table
profilePictureView = new ProfilePictureView(view.getContext()); // this is the profile pic view


the_maintable_row_team_spuck.removeAllViews();
the_maintable_row_team_spuck.setLayoutParams(new TableRow.LayoutParams
        ( TableRow.LayoutParams.MATCH_PARENT, TableRow.LayoutParams.MATCH_PARENT));

the_maintable_row.setBackgroundResource(R.drawable.cell_shape);


/*the_smallperson_team_spuck.setImageResource(R.drawable.the_smallperson);
the_smallperson_team_spuck.setPadding(7, 7, 15, 0);*/


profilePictureView.setPadding(7, 7, 15, 0);

//the_maintable_row.addView(the_normal_image_view);  // adding normal image view into row
the_maintable_row.addView(profilePictureView);            // adding fb profile pic view in to row

the_maintable.addView(the_maintable_row_team_spuck, new TableRow.LayoutParams
        (TableRow.LayoutParams.MATCH_PARENT, TableRow.LayoutParams.MATCH_PARENT));

感谢任何帮助，谢谢：）

Answer 1

如果要将用户个人资料图像加载到ImageView，那么您应该尝试这个

第1步 ImageView

 <ImageView
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/profile_image"
    android:layout_width="80dp"
    android:layout_height="80dp"
    android:src="@drawable/back"
    app:civ_border_width="2dp"
    app:civ_border_color="@color/colorWhite"/>

第2步将此行放在oncreate方法上，以便在打开屏幕时加载图片

new DownloadImage(imgUserProfile).execute(userProfileUrl);

第3步 MainActivity.java

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
ImageView imgUserProfile;
imgUserProfile = (ImageView).findViewById(R.id.profile_image);

适用于AcyncTask Mehod的

第4步方法名称：DownloadImage（）

 public class DownloadImage extends AsyncTask<String, Void, Bitmap> {
    CircleImageView bmImage;

    public DownloadImage(ImageView bmImage) {
        this.bmImage = (CircleImageView) bmImage;
    }

    protected Bitmap doInBackground(String... urls) {
        String urldisplay = urls[0];
        Bitmap mIcon11 = null;
        try {
            InputStream in = new java.net.URL(urldisplay).openStream();
            mIcon11 = BitmapFactory.decodeStream(in);
        } catch (Exception e) {
            Log.d("Error", e.getStackTrace().toString());

        }
        return mIcon11;
    }

    protected void onPostExecute(Bitmap result) {
        bmImage.setImageBitmap(result);
    }
}
