Android Emulator still showing Hello World

Question

So I've set up my Eclipse to have the Android SDK and ADT plugin.

I set up my AVD to have a Galaxy Nexus and Galaxy S2 emulator.

I've created a new Android project and I get my blank MainActivity which simply displays "Hello World!" which is the problem.

In the Graphical Layout, I delete the "Hello World!" text to remove it. I check in the activity_main.xml and the script containing the "Hello World!" text is no longer there. I run in either emulator and everything works, but when the app opens, "Hello World!" is still there.

Here's the xml now

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.project.MainActivity"
tools:ignore="MergeRootFrame" />

I've changed nothing except removing that text. The MainActivity.java has not been touched. Is there something I'm missing?

Answer 1

这对我来说有点奇怪，只需从fragment.xml文件中删除Hello World Text View，就可以了。

Answer 2

that xml code is just for layout when you add smthg on layout this code will be bigger,example

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >
 <Button
        android:id="@+id/bb"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/editText1"
        android:layout_centerHorizontal="true"
        android:layout_marginBottom="72dp"
        android:text="git" />

thats have only a button your code has nothing only layout
