我正在尝试启动一个 Activity,其中包括 Bundles。我现在正在尝试将此捆绑包设置为空,因为尚未将任何内容传递给此活动。
public class DailyActivities extends Activity implements OnClickListener{
TextView scoreA
int gotA;
int counter_score;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
counter_score=0;
int questions_1 = 26;
initialize();
///////PSEUDO CODE...this is where Im trying to say, if no bundled is passed,
////////then setText for scoreA to the int counter score,
////////so that the activity doesn't crash due to null pointer exception////
Bundle gotA = getIntent().getExtras();
if(gotA == null){
scoreA.setText(counter_score);
}else if (gotA != null){
gotLetterA = gotA.getInt("key");
counter_score = gotLetterA;
int percentage = (int)( gotLetterA * 100.0 / questions_1 + 0.5);
scoreA.setText(percentage);
}
}
当前活动因 android.resources not found 错误而崩溃
编辑添加的错误日志

Sooooo这里是解决方案,我很密集哈哈
Bundle gotA = getIntent().getExtras();{
if(gotA == null){ scoreA.setText("0%");
}else {
myPkg = gotA.getInt("key");
counter_score = myPkg;
int percentage = (int)( myPkg * 100.0 / questions_1 + 0.5);
scoreA.setText(""+percentage);
}
}
