I get the following error
06-01 10:59:20.908: ERROR/AndroidRuntime(664): FATAL EXCEPTION: main

InstructionDialog.java:34 is the last line of code which is "alertDialog.show()". Can any one suggest me how to correct this. And following is the instructions.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/layout_root"
android:orientation="horiz开发者_开发知识库ontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dp"
>
<TextView android:id="@+id/title"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:textColor="#FFF"
/>
<ImageView android:id="@+id/image"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_marginRight="10dp"
/>
<TextView android:id="@+id/text"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:textColor="#FFF"
/>
</LinearLayout>
Make the mcontext to be public and set try
mContext =this in oncreate method
and use this while inflating the alertdialog.... I have been hit by this problem many a times... The only solution that i use to solve this is this one...
Hope this helps...
Try changing
View layout = inflater.inflate(R.layout.instructions, (ViewGroup) activity.findViewById(R.id.layout_root));
to
View layout = inflater.inflate(R.layout.instructions, null);
I think your top-level layout ID layout_root isn't being found by the inflater
try this
AlertDialog.Builder alert = new AlertDialog.Builder(activity.this);
LayoutInflater factory = LayoutInflater.from(activity.this);
View layout =factory.inflate(R.layout.instructions,null);
TextView t = (TextView)layout.findViewById(R.id.text);
t.setText("message");
alert.setView(layout);
