ok,
what i am trying to do is to embed a custom view in the default layout
main.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android";
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<com.lam.customview.CustomDisplayView
android:id="@+id/custom_display_view1"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<Button
android:id="@+id/prev"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_weight="50"
android:textAppearance="?android:attr/textAppearanceSmall"
android:text="@string/prev" />
</LinearLayout>
</LinearLayout>
as you can see the class is called
com.lam.customview.CustomDisplayView, with the id of
custom_display_view1.
now in the com.lam.customview.CustomDisplayView class, i want to use
another layout called
custom_display_view.xml because i don't want to programmatically
create controls/widgets.
custom_display_view.xml is just a button and an image, the content of
which i want to change
based on certain conditions:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/
android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:id="@+id/display_text_view1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello"
/>
<ImageView
android:id="@+id/display_image_view1"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</ImageView>
</LinearLayout>
i tried to do:
1) public CustomDisplayView(Context context, AttributeSet attrs) {
super(context, attrs);
try
{
// register our interest in hearing about changes to our
surface
SurfaceHolder holder = getHolder();
holder.addCallback(this);
View.inflate(context, R.layout.custom_display_view, null);
...
but got this error, "03-08 20:33:15.711: ERROR/onCreate(10879): Binary
XML file line #8:
Error inflating class java.lang.reflect.Constructor
".
2) public CustomDisplayView(Context context, AttributeSet attrs) {
super(context, attrs);
try
{
// register our interest in hearing about changes to our
surface
SurfaceHolder holder = getHolder();
holder.addCallback(this);
View.inflate(context, R.id.custom_display_view1, null);
...
but got this error, "03-08 20:28:47.401: ERROR/
CustomDisplayView(10806): Resource ID
#0x7f050002 type #0x12 is not valid
"
also, if i do it this way, as someone has suggested, it's not clear to
me how the
custom_display_view.xml is associated with the custom view class.
thanks.
