好的所以这是下面的活动：
@Override
protected void onCreate(Bundle foodActivityState) {
super.onCreate(foodActivityState);
setContentView(R.layout.food_activity);
backgroundimage = (View) findViewById(R.id.food_background);
background = backgroundimage.getBackground();
//background.setAlpha(50);
editText_foodActivity = (EditText) findViewById(R.id.editText_foodActivity);
editText_foodActivity.setInputType(InputType.TYPE_CLASS_NUMBER);
done = (Button) findViewById(R.id.button1_foodActivity);
done.setOnClickListener(this);
back = (Button) findViewById(R.id.button2_foodActivity);
back.setOnClickListener(this);
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.button1_foodActivity:
boolean didItWork = true;
tourDB gettingInfo = new tourDB(this);
gettingInfo.open();
long getlastID = gettingInfo.getMaxID();
int prev_food = gettingInfo.getFoodPrev(getlastID);
String getAmountString = editText_foodActivity.getText().toString();
int getAmountInt = Integer.parseInt(getAmountString);
prev_food = prev_food + getAmountInt;
int prev_remainbudget = gettingInfo.getPrevRemainBudget(getlastID);
prev_remainbudget = prev_remainbudget - getAmountInt;
try{
gettingInfo.updatePrevRemainBudget(getlastID, prev_remainbudget);
gettingInfo.updatefoodEntry(getlastID, prev_food);
gettingInfo.close();
}catch(Exception e){
didItWork = false;
String error = e.toString();
Dialog d = new Dialog(this);
d.setTitle("Not Updated");
TextView tv = new TextView(this);
tv.setText(error);
d.setContentView(tv);
d.show();
} finally {
if (didItWork) {
Dialog d = new Dialog(this);
d.setTitle("Data Updated");
d.show();
}
Intent openonGoingActivity = new Intent("com.blackcat.blackcattourorganizer.ONGOINGACTIVITY");
startActivity(openonGoingActivity);
}
break;
case R.id.button2_foodActivity:
Intent openonGoingActivity = new Intent("com.blackcat.blackcattourorganizer.ONGOINGACTIVITY");
startActivity(openonGoingActivity);
break;
}
}
}
现在给出了xml文件：
<EditText
android:id="@+id/editText_foodActivity"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="50dp"
android:hint="@string/edit_expence">
</EditText>
<Button
android:id="@+id/button1_foodActivity"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="50dp"
android:text="@string/done_expense"/>
<Button
android:id="@+id/button2_foodActivity"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="50dp"
android:text="@string/back_expense"/>
为什么意图不起作用？
