我想在android studio中制作货币转换应用,但我无法在模拟器中启动我的应用,我相信这是因为编码中的一些错误,我将在这里复制我的代码,所以你可以帮助我,我将感激不尽。)
public class MainActivity extends AppCompatActivity {
public void clickFunction(View view) {
Log.i ("Info", "Button pressed");
EditText editText = (EditText) findViewById(editText);
Log.i( "Values" ,editText,getText().toString());
String amountInEuros = editText.getText()
Log.i("Info" , String.valueOf(editText.getText()));
String getAmountInEuros ;
double amountInEuros double = double.parsedouble (amountInEuros);
double amountInDollars double = double amountInEuros double * 1.08 ;
String amountInDollars String = double.toString (amountInDollars double)
Log.i("Amount in Dollars", amountInDollars String);
Toast.makeText ( this , amountInEuros + "Euros" + "is" + amountInDollars String , LENGTH_LONG );
}
这些行缺少一个分号。
String amountInEuros = editText.getText();
String amountInDollars String = double.toString (amountInDollars double);
