Java StarActivityForResult（）导致在返回意图数据时强制关闭

java android

Java StarActivityForResult（）导致在返回意图数据时强制关闭,java,android,android-intent,android-activity,Java,Android,Android Intent,Android Activity,以下是我代码的一部分： @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case R.id.menu_settings: startActivityForResult(new Intent(MainActivity.this,Settings.class),1); break; } return

以下是我代码的一部分：

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {

    case R.id.menu_settings:

        startActivityForResult(new Intent(MainActivity.this,Settings.class),1);
        break;
    }
    return true;
}


@Override
public void onActivityResult(int requestCode,int resultCode,Intent data) {

    Toast.makeText(getBaseContext(),requestCode, Toast.LENGTH_SHORT); // This was causing the error. See the fantastic answer that's been provided for details. Comment out this this and it works !

    if(requestCode==1) {
        if(resultCode==RESULT_OK) 
        {
            String extraData=data.getData().toString();

            minD=Integer.parseInt(extraData);
            Toast.makeText(getBaseContext(),minD, Toast.LENGTH_SHORT);
        }

    }

}

下面是Settings.java的代码

package com.example.com.draft1;

import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;



public class Settings extends Activity  {



@Override 

public void onCreate(Bundle savedInstanceState)
{

    super.onCreate(savedInstanceState);
    setContentView(R.layout.settings);


    Button setbtn = (Button) findViewById(R.id.SetminDistance);


    setbtn.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {

        //Intent data=new Intent();
        EditText mind=(EditText) findViewById(R.id.minDistance);
                    String minDis =mind.getText().toString();
                    Intent data = new Intent();   
                    data.setData(Uri.parse(minDis));

        Toast.makeText(getBaseContext(), minDis, Toast.LENGTH_SHORT).show();
                  //  intent.putExtra("minD", minDis);





       if (getParent() == null) {
           setResult(RESULT_OK, data);
       } else {
           getParent().setResult(RESULT_OK, data);
       }
       finish();



      /*  setResult(RESULT_OK, data);
       finish();*/
            }

});

}
}

现在，当我为设置选择菜单选项时，所需的活动会完全打开，但是，当我尝试返回数据时，它会导致强制关闭
以下是显示错误的Logcat读数：

为什么我会在附近遇到一股力量
我真的很感谢你的帮助
谢谢你对这个问题感兴趣
根据建议

if(requestCode==1) { if(resultCode==RESULT_OK) { //String extraData=data.getData().toString(); //minD=Integer.parseInt(extraData); Toast.makeText(getBaseContext(),String.valueOf(requestCode), Toast.LENGTH_SHORT).show(); }
如果你看到
所以，若您将第二个参数设置为
int
，那个么系统将在R.java中查找该id，但讽刺的是，实际上您想要打印数字，所以只需将第二个参数设置为
String
，即
将Toast行代码更改为

Toast.makeText(getBaseContext(),requestCode+"", Toast.LENGTH_SHORT).show();

您应该使用minent.putExtra而不是uri。。。请检查此代码
MainActivity.java

@Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case R.id.menu_settings: startActivityForResult(new Intent(MainActivity.this, Settings.class), 1); break; } return true; } @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == 1) { if (resultCode == RESULT_OK) { minD = Integer.parseInt(data.getStringExtra("data")); Toast.makeText(MainActivity.this, String.valueOf(minD), Toast.LENGTH_SHORT); } } }`

资源$NotFoundException:字符串资源ID#0x1“
@Keyser感谢您的回复。你能解释一下吗？我是android新手，因此我在理解Logcat入口时遇到了一点困难抱歉，不能给你更多，但这就是强制关闭的原因。查看所有字符串资源代码。@CapDroid我已编辑了问题，以包含完整的Logcat erroryour error在此类Main活动中的570行。。这行是什么？
