java.lang.NumberFormatException : Invalid int: "android. support.v7.internal.widget.TintEditText

Question

我有代码将两个文本框中的两个数字相加。

    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}"

请粘贴以下工作代码。我刚刚运行并检查了它。

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);
    }
