将bundle传递给if语句

活动声明—->有2个button和一个textView （获取总金额）

Activity Project1和Petrol —–>一个editText和一个保存button

活动索赔

  button1.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { AlertDialogRadio(a1); } }); button2.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { AlertDialogRadio(a2); } }); public void AlertDialogRadio(final int k) { final CharSequence[] ClaimsModel = {"Project1", "Petrol"}; AlertDialog.Builder alt_bld = new AlertDialog.Builder(getActivity()); alt_bld.setTitle("Select a Claims"); alt_bld.setSingleChoiceItems(ClaimsModel, -1, new DialogInterface .OnClickListener() { public void onClick(DialogInterface dialog, int item) { if (item == 0) { Intent intent = new Intent(getActivity().getApplicationContext(), Project1.class); intent.putExtra("k",k); startActivityForResult(intent, 0); } else if (item == 1) { Intent intent = new Intent(getActivity().getApplicationContext(), Petrol.class); intent.putExtra("k", k); startActivityForResult(intent, 1); } 

** Project1或Petrol，取决于……）**

  public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.project); text= (EditText)findViewById(R.id.editText1); Button save=(Button)findViewById(R.id.button12); save.setOnClickListener(new View.OnClickListener() { public void onClick(View arg0) { Intent returnIntent = new Intent(); l="A"; text = text.getText().toString(); returnIntent.putExtra("text", text); returnIntent.putExtra("l", l); final int k1 = getIntent().getExtras().getInt("k"); returnIntent.putExtra("k1", k1); setResult(Activity.RESULT_OK, returnIntent); finish(); } }); } @Override public void onBackPressed() { Intent returnIntent = new Intent(); setResult(Activity.RESULT_CANCELED, returnIntent); finish(); } 

是否可以将bundle传递给if statement ？ 我想将值传递给另一个案例，最后总计两个值。 我怎样才能做到这一点？ 现在我只得到值和bs ，但不是值amount 。 我相信它需要为if statement添加一个bundle …

继续Claims.java ….

  public void onActivityResult(int requestCode, int resultCode, Intent data) { int button = data.getIntExtra("k1", 0); // to check which button was pressed long a=0; long as=0; long bs=0; String result; String result1; if (button == 1) { switch (requestCode) { case 0: result = data.getStringExtra("text"); String b = data.getStringExtra("l"); as=Long.parseLong(result); c.setText(" " + b + "------" + "RM " + result); Toast.makeText(getActivity(),as+"", Toast.LENGTH_LONG).show(); break; case 1: result = data.getStringExtra("text"); String b1 = data.getStringExtra("l"); as=Long.parseLong(result); c.setText(" " + b1 + "------" + "RM " + result); Toast.makeText(getActivity(),as+"", Toast.LENGTH_LONG).show(); break; } if(button==2) { switch (requestCode) { case 0: result1 = data.getStringExtra("text"); String b = data.getStringExtra("l"); bs=Long.parseLong(result1); d.setText(" " + b + "------" + "RM " + result1); Toast.makeText(getActivity(),bs+"", Toast.LENGTH_LONG).show(); break; case 1: result1 = data.getStringExtra("text"); String b1 = data.getStringExtra("l"); bs=Long.parseLong(result1); d.setText(" " + b1 + "------" + "RM " + result1); Toast.makeText(getActivity(),bs+"", Toast.LENGTH_LONG).show(); break; } } else if(requestCode==CAMERA_REQUEST_CODE) { } long amount=as+bs; Toast.makeText(getActivity(),amount+"", Toast.LENGTH_LONG).show(); 

我指的是如何通过另一个if语句中的bundle传递一个在if语句中创建的字符串值？ 但答案对我来说还不清楚。

吐司应该显示1 12 13但我得到1 12 12.似乎值1不能添加！

您应该将您在onActivityResult中传递的值存储在Activity的变量中，然后直接读取Toast的这些变量。

 public class Claims{ long a, as, bs; public void onActivityResult(int requestCode, int resultCode, Intent data) { int button = data.getIntExtra("k1", 0); String result; if (button == 1) { result = data.getStringExtra("text"); as=Long.parseLong(result); } else if(button==2) { result = data.getStringExtra("text"); bs=Long.parseLong(result1); } long amount=as+bs; Toast.makeText(getActivity(),amount+"", Toast.LENGTH_LONG).show(); } } 

您仍然需要根据您的标准初始化您的值。
