如何在EditText中设置数值？

Question

我想制作一个简单的计算器我的代码如下:

package som.dev.android.calc;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;

public class CalcApp extends Activity {
    /** Called when the activity is first created. */
    Button addValues, subValues, equalsValue;
    EditText inputValue;

    int inputNum = 0;
    public int value1;
    public int value2;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        // initializing Views
        inputValue = (EditText) findViewById(R.id.editText1);
        addValues = (Button) findViewById(R.id.addBtn);
        subValues = (Button) findViewById(R.id.subBtn);
        equalsValue = (Button) findViewById(R.id.equalsBtn);

        // adding onClick Listeners
        addValues.setOnClickListener(new View.OnClickListener() {
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
                pressed = true;
                value1 = Integer.parseInt(inputValue.getText().toString());
                inputValue.setText("");
            }
        });

        equalsValue.setOnClickListener(new View.OnClickListener() {
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
                value2 = Integer.parseInt(inputValue.getText().toString());
                int result = value1+value2;

                inputValue.setText(result);// There an exception occurs....
            }
        });
    }
}

但它没有将结果设置为我的应用程序中的Edittext并且发生异常并且消息来了不幸的是应用程序被收集了类似的东西所以请任何人告诉我这个问题的解决方案

Answer 1

用这个inputValue.setText(""+result);代替inputValue.setText(result);// There an exception occurs....

只需将整数转换为字符串
