我有代码将两个文本框中的两个数字加在一起。
public void sumNumbers(View v){
EditText input1 = (EditText) findViewById(R.id.input1);
int calc1 = Integer.parseInt(String.valueOf(input1));
EditText input2 = (EditText) findViewById(R.id.input2);
int calc2 = Integer.parseInt(String.valueOf(input2));
int total = calc1 + calc2;
String result = String.valueOf(total);
EditText output1 = (EditText)findViewById(R.id.output);
output1.setText(result);
}
但是，当我启动应用程序并按下按钮时，我崩溃了：
Caused by: java.lang.NumberFormatException: Invalid int: "android.support.v7.internal.widget.TintEditText{b412b358 VFED..CL ........ 292,60-392,100 #7f080041 app:id/input1}"

帮帮我？
最佳答案
请粘贴以下工作代码。我刚刚跑步并检查了一下。
public void sumNumbers(View v){
EditText input1 = (EditText) findViewById(R.id.input1);
int calc1 = Integer.parseInt(String.valueOf(input1.getText()));
EditText input2 = (EditText) findViewById(R.id.input2);
int calc2 = Integer.parseInt(String.valueOf(input2.getText()));
int total = calc1 + calc2;
String result = String.valueOf(total);
EditText output1 = (EditText)findViewById(R.id.output);
output1.setText(result);
}
