将安卓自定义VIew转换为代码

Question

我想将此XML文件转换为自定义视图，但它不起作用：

<?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="wrap_content">

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="80dp"
        android:layout_height="80dp"
        android:src="@drawable/ic_launcher" />

    <RelativeLayout
        android:id="@+id/relativeLayout1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@+id/imageView1">

        <TextView
            android:id="@+id/posted_content_user"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="posted_content_user"
            android:textAppearance="?android:attr/textAppearanceMedium" />

        <TextView
            android:id="@+id/posted_content_date"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignBottom="@+id/posted_content_user"
            android:layout_alignParentRight="true"
            android:text="59m"
            android:textAppearance="?android:attr/textAppearanceSmall" />
    </RelativeLayout>

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/relativeLayout1"
        android:layout_alignParentRight="true"
        android:layout_below="@+id/relativeLayout1"
        android:text="TextView 183091480914809 11rh1h23 k1j2h 3oi12u 3o12h3kj12h3iu12 h3kj12h3 12uy3h12kjh31 i2uy3ijh" />

</RelativeLayout>

它应该是这样的：

这是我生成的视图的代码

public void generateView(Context context) {
    this.setLayoutParams(new RelativeLayout.LayoutParams(
            LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));

    // Contacts Pictures
    ivContactPictures = new ImageView(context);
    ivContactPictures.setLayoutParams(new RelativeLayout.LayoutParams(80,
            80));

    // RelativeLayout
    RelativeLayout relLayoutContent = new RelativeLayout(context);
    RelativeLayout.LayoutParams relLayoutContentParams = new RelativeLayout.LayoutParams(
            LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
    relLayoutContentParams.addRule(RIGHT_OF, ivContactPictures.getId());
    relLayoutContent.setLayoutParams(relLayoutContentParams);

    // RelativeLayout -> TextView Post User
    posted_content_user = new TextView(context);
    posted_content_user.setLayoutParams(new RelativeLayout.LayoutParams(
            LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
    // posted_content_user.setTextAppearance(context,
    // R.attr.textAppearanceMedium);

    // RelativeLayout -> TextView Time
    posted_content_date = new TextView(context);
    RelativeLayout.LayoutParams posted_content_dateParams = new RelativeLayout.LayoutParams(
            LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
    // posted_content_user.setTextAppearance(context,
    // R.attr.textAppearanceSmall);
    posted_content_dateParams.addRule(ALIGN_BOTTOM,
            posted_content_user.getId());
    posted_content_dateParams.addRule(ALIGN_PARENT_RIGHT);
    posted_content_date.setLayoutParams(posted_content_dateParams);

    // textView Content
    posted_content = new TextView(context);
    RelativeLayout.LayoutParams posted_contentParams = new RelativeLayout.LayoutParams(
            LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
    posted_contentParams.addRule(ALIGN_LEFT, relLayoutContent.getId());
    posted_contentParams.addRule(ALIGN_PARENT_RIGHT);
    posted_contentParams.addRule(BELOW, relLayoutContent.getId());
    posted_content.setLayoutParams(posted_contentParams);

    // Add RelativeLayout
    this.addView(ivContactPictures);
    relLayoutContent
            .addView(posted_content_user);
    relLayoutContent
            .addView(posted_content_date);
    this.addView(relLayoutContent);
    this.addView(posted_content);

}

我的代码有什么问题吗？

这不是生成自定义视图的方式--或者至少很难实现。您应该做的是创建一个子视图子视图，它将xml扩展到自身作为父视图。这将使该类等同于xml文件的全部内容。然后，您可以提供任何合适的getter/setter/其他功能。
