把它放在你的 MainActivity 中:
{
public EditText bizname, storeno, rcpt, item, price, tax, total;
public Button click, click2;
int contentView;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate( savedInstanceState );
setContentView( R.layout.main_activity );
bizname = (EditText) findViewById( R.id.editBizName );
item = (EditText) findViewById( R.id.editItem );
price = (EditText) findViewById( R.id.editPrice );
tax = (EditText) findViewById( R.id.editTax );
total = (EditText) findViewById( R.id.editTotal );
click = (Button) findViewById( R.id.button );
}
}
把它放在按钮或其他东西下
public void clickBusiness(View view) {
checkPermsOfStorage( this );
bizname = (EditText) findViewById( R.id.editBizName );
item = (EditText) findViewById( R.id.editItem );
price = (EditText) findViewById( R.id.editPrice );
tax = (EditText) findViewById( R.id.editTax );
total = (EditText) findViewById( R.id.editTotal );
String x = ("\nItem/Price: " + item.getText() + price.getText() + "\nTax/Total" + tax.getText() + total.getText());
Toast.makeText( this, x, Toast.LENGTH_SHORT ).show();
try {
this.WriteBusiness(bizname,storeno,rcpt,item,price,tax,total);
String vv = tax.getText().toString();
System.console().printf( "%s", vv );
//new XMLDivisionWriter(getString(R.string.SDDoc) + "/tax_div_business.xml");
} catch (ReflectiveOperationException e) {
e.printStackTrace();
}
}
那里!争论已定!
