私はアンドロイドの開発者サイトで与えられた "Form Stuff"の例を試しています。しかし、エミュレータでは、アプリケーションが予期せず動作を停止したというメッセージが表示され続けます。私はサイトのコードを完全にコピーしましたが、これは起こっているようです。私は何を間違えているのですか？Hello Form Stuffアプリケーションの問題がエミュレータで動作しない
HelloFormStuff2.java：
package com.android.HelloLinearLayouts;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;
public class HelloFormStuff2 extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// Perform action on clicks
Toast.makeText(HelloFormStuff2.this,
"Beep Bop",
Toast.LENGTH_SHORT).show();
}
});
}
}
main.xmlファイル：
<?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"
>
<Button
android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="10dp"
android:background="@drawable/android_button" />
</LinearLayout>
がandroid_button.xml：
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/android_pressed"
android:state_pressed="true" />
<item android:drawable="@drawable/android_focused"
android:state_focused="true" />
<item android:drawable="@drawable/android_normal" />
</selector>
私は何をすべき？
