チェックボックスの状態が false から true に変わらない理由を知りたいです。

here からチェックボックスの状態を設定する方法や他の投稿を読んでみましたが、コードの何が問題なのかわかりません。

私のJavaコード:

public class OrderActivity extends Activity implements OnClickListener{
public static String orderOne = null;
public static String orderTwo = null;
public static String orderThree = null;
public static String orderFour = null;
public static String orderFive = null;
public static String orderSix = null;

CheckBox chkChickenBreast, chkChickenWings, chkChickenTighs, chkWholeChicken, chkSpicyWings, chkChickenFillet;



@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_order);

    chkChickenBreast = (CheckBox) findViewById(R.id.check_box_order1);
    chkChickenWings = (CheckBox) findViewById(R.id.check_box_order2);
    chkChickenTighs = (CheckBox) findViewById(R.id.check_box_order3);
    chkWholeChicken = (CheckBox) findViewById(R.id.check_box_order4);
    chkSpicyWings = (CheckBox) findViewById(R.id.check_box_order5);
    chkChickenFillet = (CheckBox) findViewById(R.id.check_box_order6);

    Button checkOutOrder = (Button) findViewById(R.id.button_confirm_order);
    checkOutOrder.setOnClickListener(this);

    Button backToMain = (Button) findViewById(R.id.button_back_to_main);
    backToMain.setOnClickListener(this);


}

@Override
public void onClick (View view) {
    String[] orderedProduct = new String[6];

    if (view.getId() == R.id.check_box_order1){
        if (chkChickenBreast.isChecked()){
            chkChickenBreast.setChecked(true);
            orderedProduct[0] = "True"; 
        }
        else{
            chkChickenBreast.setChecked(false);
            orderedProduct[0] = "False";
        }
    }               

    if (view.getId() == R.id.button_confirm_order){         
        Intent goToReceipt = new Intent(this, ReceiptActivity.class);

        if (chkChickenWings.isChecked() == true)
            orderedProduct[1] = "True";                 
        else
            orderedProduct[1] = "False";

        if (chkChickenTighs.isChecked() == true)
            orderedProduct[2] = "True";                 
        else
            orderedProduct[2] = "False";

        if (chkWholeChicken.isChecked() == true)
            orderedProduct[3] = "True";                 
        else
            orderedProduct[3] = "False";

        if (chkSpicyWings.isChecked() == true)
            orderedProduct[4] = "True";                 
        else
            orderedProduct[4] = "False";

        if (chkChickenFillet.isChecked() == true)
            orderedProduct[5] = "True";                 
        else
            orderedProduct[5] = "False";

        goToReceipt.putExtra(orderOne, orderedProduct[0]);
        goToReceipt.putExtra(orderTwo, orderedProduct[1]);
        goToReceipt.putExtra(orderThree, orderedProduct[2]);
        goToReceipt.putExtra(orderFour, orderedProduct[3]);
        goToReceipt.putExtra(orderFive, orderedProduct[4]);
        goToReceipt.putExtra(orderSix, orderedProduct[5]);

        startActivity(goToReceipt);
    }
    else if (view.getId() == R.id.button_back_to_main){
        onBackPressed();
        //Intent goToMenu = new Intent(this, MainActivity.class);
        //startActivity(goToMenu);
    }
}



@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}
}

私のXMLコードは次のとおりです。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:id="@layout/activity_main"
android:layout_width="match_parent"

android:gravity="center_horizontal"
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" >

<ImageView
    android:id="@+id/image_robinsons_logo"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:contentDescription="@string/robinsons_picture_title"
    android:src="@drawable/rsc" />

<ScrollView
    android:id="@+id/scroll_order_product"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

    <TableLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:stretchColumns="0,1,2" >

        <TableRow
            android:id="@+id/table_row_title"
            android:layout_width="fill_parent" >

            <TextView
                android:id="@+id/text_view_title_name"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center"
                android:gravity="center"
                android:textSize="12sp"
                android:text="@string/row_title_name" />

            <TextView
                android:id="@+id/text_view_title_price"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center"
                android:gravity="center"
                android:textSize="12sp"
                android:text="@string/row_title_price" />

            <TextView
                android:id="@+id/text_view_title_image"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center"
                android:gravity="center"
                android:textSize="12sp"
                android:text="@string/row_title_image" />

        </TableRow>
    </TableLayout>
</ScrollView>

次に、別のアクティビティに転送します。

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_receipt);

    Intent goToReceipt = getIntent();
    String boolOrderOne = goToReceipt.getStringExtra(OrderActivity.orderOne);

    if (boolOrderOne == "True"){
        TextView orderOne = new TextView(this);
        orderOne.setText(boolOrderOne);
        setContentView(orderOne);
    }
}

このフォームを試してください:

これはoncreatのコードを切り取った：

    check = (CheckBox) findViewById(R.id.checkBox);
    // get state of checkbox
    boolean isChecked = getBooleanFromPreferences("isChecked");
    // set state checkbox
    check.setChecked(isChecked);

    // invoked if status change
    check.setOnCheckedChangeListener(new OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton view, boolean isChecked) {
            CheckInActivity.this.putBooleanInPreferences(isChecked,
                    "isChecked");
        }
    });

    check.setOnClickListener(isCheckBoxClicked);

方法:

public void putBooleanInPreferences(boolean isChecked, String key) {

    SharedPreferences sp = this.getPreferences(Activity.MODE_PRIVATE);
    SharedPreferences.Editor editor = sp.edit();
    editor.putBoolean(key, isChecked);
    editor.commit();

}


public boolean getBooleanFromPreferences(String key) {

    SharedPreferences sp = this.getPreferences(Activity.MODE_PRIVATE);
    Boolean isChecked = sp.getBoolean(key, false);
    return isChecked;

}

// if state of checkbox is true
private OnClickListener isCheckBoxClicked = new OnClickListener() {
    public void onClick(View v) {

        if ((check.isChecked())) {

          // Your code if checkbox state is true

        } else {


        }
    }

};
