Is it possible to dynamically add AndroidAnnotation @EViewGroups instead of using the traditional inflate directly?

问题

I'm trying to use Android Annotations and dynamically add layout components when my createNewRow button is clicked. The app runs and displays the default rows defined in activity_main.xml and, after clicking createNewButton I see children attached to my dynamicTable in the debugger but the new children are not displayed. Here is my main activity XML:

activity_main.xml

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              xmlns:tools="http://schemas.android.com/tools"
              android:id="@+id/inflateLayout"
              android:orientation="vertical"
              android:layout_width="match_parent"
              android:layout_height="match_parent"
              android:paddingLeft="@dimen/activity_horizontal_margin"
              android:paddingRight="@dimen/activity_horizontal_margin"
              android:paddingTop="@dimen/activity_vertical_margin"
              android:paddingBottom="@dimen/activity_vertical_margin"
              tools:context="net.richardriley.inflate.app.MainActivity">

    <Button
        android:id="@+id/createNewRow"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/newRowButton"/>

    <TableLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/dynamicTable">

        <TableRow>

            <TextView
                android:text="@string/hello_world"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"/>

        </TableRow>

    </TableLayout>
</LinearLayout>

So simply a linear layout with a button and then a table container. Clicking createNewRow should add a new InflatedRow. Here is the XML for the row I want to dynamically add:

inflatedrow.xml

<?xml version="1.0" encoding="utf-8"?>

<merge xmlns:android="http://schemas.android.com/apk/res/android" >

        <TextView
            android:id="@+id/inflatedRowTextView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/inflatedRowLabel"/>
        <Button
            android:id="@+id/inflatedRowButton"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/defaultNewRowText"
            />

</merge>

Using AA my subclass for a tableRow is

InflatedRow.java

package net.richardriley.inflate.app;

import android.content.Context;
import android.widget.Button;
import android.widget.TableRow;
import android.widget.TextView;
import org.androidannotations.annotations.EViewGroup;
import org.androidannotations.annotations.ViewById;

/**
 * inflate : Created by rgr on 20/03/14.
 */
@EViewGroup(R.layout.inflatedrow)
public class InflatedRow extends TableRow {

    @ViewById
    Button inflatedRowButton;

    @ViewById
    TextView inflatedRowTextView;

    public InflatedRow(Context context) {
        super(context);
    }
}

and finally my main activity java itself:

MainActivity.java

package net.richardriley.inflate.app;

import android.support.v7.app.ActionBarActivity;
import android.widget.LinearLayout;
import android.widget.TableLayout;
import org.androidannotations.annotations.*;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import static ch.qos.logback.classic.android.BasicLogcatConfigurator.configureDefaultContext;

@OptionsMenu(R.menu.main)
@EActivity(R.layout.activity_main)
public class MainActivity extends ActionBarActivity {

    static {
        configureDefaultContext();
        log = LoggerFactory.getLogger(MainActivity.class);
    }

    @ViewById
    LinearLayout inflateLayout;

    @ViewById
    TableLayout dynamicTable;

    public MainActivity() {
    }

    protected static Logger log;

    @Click
    void createNewRow() {
        log.info("clicked");
        InflatedRow_ inflatedRow=new InflatedRow_(this);
        dynamicTable.addView(inflatedRow,0);
        /*LayoutInflater layoutInflater= (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View view = layoutInflater.inflate(R.layout.inflatedrow,null);
        dynamicTable.addView(view);*/
    }

    @OptionsItem
    void openSettingsSelected(){
        log.info("Hello");
    }

}

In createNewRow if I use the inflater service directly it works.

What am I missing?

many thanks.

回答1:

Don't use the annotated class when you're inflating the view and make sure you're calling the build method that inflates it.

@Click
void createNewRow() {
    log.info("clicked");
    InflatedRow inflatedRow = new InflatedRow_.build(this);
    dynamicTable.addView(inflatedRow,0);

}

回答2:

instead of 'View inflatedRow= new InflatedRow_(this);' I use 'View inflatedRow=InflatedRow_.build(this);'. This is documented for custom controls and I needed to do it for a merged control group too. So mea culpa to a degree!

@Click
    void createNewRow() {
        log.info("clicked");
        InflatedRow_ inflatedRow=InflatedRow_.build(this);
        dynamicTable.addView(inflatedRow,0);
    }

Alternatively (and no idea if this would continue to be supported:

@Click
    void createNewRow() {
        log.info("clicked");
        /*View inflatedRow = InflatedRow_.build(this);*/
        InflatedRow_ inflatedRow = new InflatedRow_(this);
        inflatedRow.onFinishInflate();
        dynamicTable.addView(inflatedRow, 0);

    }
