现在确定未打开的 Activity 的代码

public class showBudgetActivity extends Activity {

TextView sb1, sb2, sb3, sb4, sb5, sb_r;

Button showBudget_backButton;

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

    sb_r = (TextView) findViewById(R.id.textView_showBudget_rBudget);

    sb1 = (TextView) findViewById(R.id.textView_SB_H2);
    sb2 = (TextView) findViewById(R.id.textView_SB_T2);
    sb3 = (TextView) findViewById(R.id.textView_SB_F2);
    sb4 = (TextView) findViewById(R.id.textView_SB_S2);
    sb5 = (TextView) findViewById(R.id.textView_SB_O2);

    showBudget_backButton = (Button) findViewById(R.id.button_showBudget);


    tourDB gettingInfo = new tourDB(this);

    gettingInfo.open();

    long getlastID = gettingInfo.getMaxID();

    int prev_remainbudget = gettingInfo.getPrevRemainBudget(getlastID);

    int prev_rent = gettingInfo.getRentPrev(getlastID);
    int prev_transport = gettingInfo.getTransportPrev(getlastID);
    int prev_food = gettingInfo.getFoodPrev(getlastID);
    int prev_shopping = gettingInfo.getShoppingPrev(getlastID);
    int prev_other = gettingInfo.getOtherPrev(getlastID);

    gettingInfo.close();

    sb_r.setText(prev_remainbudget);

    sb1.setText(String.valueOf(prev_rent));
    sb2.setText(String.valueOf(prev_transport));
    sb3.setText(String.valueOf(prev_food));
    sb4.setText(String.valueOf(prev_shopping));
    sb5.setText(String.valueOf(prev_other));

    showBudget_backButton.setOnClickListener(new Button.OnClickListener() {  
        public void onClick(View v)
            {
                Intent openonGoingActivity = new Intent("com.blackcat.blackcattourorganizer.ONGOINGACTIVITY");
                startActivity(openonGoingActivity);
            }
         });


    //fetchdatafromDataBase();
}

/*private void fetchdatafromDataBase() {

}*/
}

现在这是我调用 Activity 的类

public class onGoingActivity extends ListActivity{

    static final String onGoingList[] = {"Enter Expenses","Remaining Budget","Click Photos","Close Tour Profile","Back"};


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setListAdapter(new onGoingArrayAdapter(this, onGoingList));
    }

    @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {

        super.onListItemClick(l, v, position, id);

        String positionItem = (String) getListAdapter().getItem(position);


        if (positionItem.contentEquals("Enter Expenses")) {

            //mainMenuActivityItem = "createNewActivity_1";

            Intent openActivity = new Intent("com.blackcat.blackcattourorganizer.EXPENSELISTACTIVITY");
            startActivity(openActivity);

        }else if (positionItem.contentEquals("Remaining Budget")) {

            //mainMenuActivityItem = "onGoingActivity";

            Intent openActivity = new Intent("com.blackcat.blackcattourorganizer.SHOWBUDGETACTIVITY");
            startActivity(openActivity);

        }else if (positionItem.contentEquals("Click Photos")) {

            //mainMenuActivityItem = "tourListActivity";

            Intent openActivity = new Intent("com.blackcat.blackcattourorganizer.PHOTOUPACTIVITY");
            startActivity(openActivity);

        }else if (positionItem.contentEquals("Famous Tourist Attractions")) {

            //mainMenuActivityItem = "famousTourActivity";

            Intent openActivity = new Intent("com.blackcat.blackcattourorganizer.CLOSEPROFILEACTIVITY");
            startActivity(openActivity);

        }else if (positionItem.contentEquals("Back")) {

            //mainMenuActivityItem = "alarmSetActivity";

            Intent openMainActivity = new Intent("com.blackcat.blackcattourorganizer.MAINACTIVITY");
            startActivity(openMainActivity);
        }

        /*

        if (selectExpense == "back"){
            Intent openMainActivity = new Intent("com.blackcat.blackcattourorganizer.MAINACTIVITY");
            startActivity(openMainActivity);
        }
        else {

        try{
            Class onGoingClass = Class.forName("com.blackcat.blackcattourorganizer." + selectExpense);
            Intent selectExpenseIntent = new Intent(onGoingActivity.this, onGoingClass);
            startActivity(selectExpenseIntent);
        }catch(ClassNotFoundException e){
            e.printStackTrace();
            }
        }*/
    }
}

清单非常好。

Answer 1

你忘了给你的sb_r打电话String.valueOf()TextView

简单地做：

sb_r.setText(String.valueOf(prev_remainbudget));

TextView 的setText() 方法试图找到一个与该数字匹配的资源id，如果你给它一个任意的int 值，它就找不到资源，因此Exception，

Answer 2

您似乎引用了一个不存在的资源，请检查您的代码中的所有 R.x 使用情况是否存在于您的资源中

 android.content.res.Resources$NotFoundException: String resource ID #0xc80
