android–setText无法在TextView中将数字显示为文本

概述我有4个按钮和1个TextView.我希望每个按钮在TextView中从值(解析为int)中添加或减去不同的量.当我点击其中一个按钮时,它会抛出致命错误(如下所示).我搜索了一些其他Stackoverflow讨论,似乎没有任何工作.这是我目前的活动：publicclassPaydownSnowballextendsActivity{intaA

我有4个按钮和1个TextVIEw.我希望每个按钮在TextVIEw中从值(解析为int)中添加或减去不同的量.当我点击其中一个按钮时,它会抛出致命错误(如下所示).我搜索了一些其他Stackoverflow讨论,似乎没有任何工作.这是我目前的活动：

public class Paydownsnowball extends Activity {int aAmt;String debtExtraPayment;@OverrIDeprotected voID onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentVIEw(R.layout.snowball);    final button plusTen = (button) findVIEwByID(R.ID.buttonp10);    final button plusFive = (button) findVIEwByID(R.ID.buttonp5);    final button minusFive = (button) findVIEwByID(R.ID.buttonm5);    final button minusTen = (button) findVIEwByID(R.ID.buttonm10);    SharedPreferences sharedPref= getSharedPreferences("chaosdatasnowball", 0);    debtExtraPayment = sharedPref.getString("debtExtraPayment", null);    debtExtraPayment ="0";    TextVIEw addamount = (TextVIEw) findVIEwByID(R.ID.dispAddamt);    addamount.setText(debtExtraPayment);    aAmt = Integer.parseInt(debtExtraPayment);    plusTen.setonClickListener(new OnClickListener() {        public voID onClick(VIEw v) {          aAmt = aAmt + 10;          TextVIEw addamount = (TextVIEw) findVIEwByID(R.ID.dispAddamt);          addamount.setText(aAmt);        }      });    plusFive.setonClickListener(new OnClickListener() {        public voID onClick(VIEw v) {          aAmt = aAmt + 5;          TextVIEw addamount = (TextVIEw) findVIEwByID(R.ID.dispAddamt);          addamount.setText(aAmt);        }      });    minusTen.setonClickListener(new OnClickListener() {        public voID onClick(VIEw v) {          aAmt = aAmt - 10;          TextVIEw addamount = (TextVIEw) findVIEwByID(R.ID.dispAddamt);          addamount.setText(aAmt);        }      });    minusFive.setonClickListener(new OnClickListener() {        public voID onClick(VIEw v) {          aAmt = aAmt - 5;          TextVIEw addamount = (TextVIEw) findVIEwByID(R.ID.dispAddamt);          addamount.setText(aAmt);        }      });    debtExtraPayment = String.valueOf(aAmt);    addamount.setText(debtExtraPayment);    SharedPreferences.Editor editor= sharedPref.edit();    editor.putString("debtExtraPayment", debtExtraPayment).commit();}

以下是点击plusFive按钮时出现的logcats：

PID: 695 SIG: 9

解决方法:

问题在于这样的线条

addamount.setText(aAmt);

其中aAmt是一个int.这会查找ID为aAmt的资源.你需要首先将它转换为String

addamount.setText(String.valueOf(aAmt));

有重载的setText()方法. See the docs

This post goes into some more detail as to how this actually works
