私はAndroidを使用していて、メニューオプションが1つあります。そのオプションをタップしたときに新しいアクティビティを開始したいのですが、開始アクティビティを実装しようとすると、常にここに力が入ります。コードは次のとおりです。

@Override
public boolean onOptionsItemSelected(MenuItem item)
{
    switch (item.getItemId()) 
    {
        case R.id.tentang :
            startActivity(new Intent(getApplicationContext(), about.class));
            finish();
            return true;
        default : 
            return super.onContextItemSelected(item);
    }
}

それを修正するアイデアはありますか？

これを試して

@Override
public boolean onOptionsItemSelected(MenuItem item) {

    //Toast.makeText(this, "You pressed the icon!", Toast.LENGTH_LONG).show();
    Intent i = new Intent(MainActivity.this, SecondActivity.class);
    startActivity(i);

    return true;
}

returnステートメントの変更：

super.onContextItemSelected(item);

に：

super.onOptionsItemSelected(item);

私はあなたの方法を修正しました：

@Override
public boolean onOptionsItemSelected(MenuItem item)
{
    switch (item.getItemId()) 
    {
        case R.id.tentang :
            startActivity(new Intent(getApplicationContext(), about.class));
            return true;
    }
    return super.onOptionsItemSelected(item);
}

アクティビティをAndroidManifest.xmlに追加しなかったと思います。アクティビティがcom.yourdomain.Aboutであると想定します。次の行をAndroidManifest.xmlに追加します。

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.yourdomain"
    android:versionCode="1"
    android:versionName="1.0">

<uses-sdk android:minSdkVersion="7" />

<application .......

<activity
    android:name=".About"
    android:label="About!" >
</activity>

この助けを願っています！

これを試して：

@Override
public boolean onOptionsItemSelected(MenuItem item){

    switch(item.getItemId()){
case R.id.tentang : 
newActivity();

};  


    return super.onOptionsItemSelected(item);
}    

    private void newActivity(){

        Intent i=new Intent();
        i.setClass(Activity.this, about.class);
        startActivity(i);   
    }

実際にあなたの問題は：

OutOfMemoryError: bitmap size exceeds VM budget.

「画像をビットマップオブジェクトにロードする際のメモリ不足の問題」が役立つ場合があります。

finish（）を削除してみてください。

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // TODO Auto-generated method stub
    Toast.makeText(this, "selected ", 20).show();
    Intent intent_details = new Intent(this, about.class);
    startActivity(intent_details);
    return true;
}
