StarActivityForResult（），導致強制關閉在返回意向數據

這裏是我的代碼段：StarActivityForResult（），導致強制關閉在返回意向數據

@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

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();*/ 
      } 

}); 

} 
}

現在的代碼時，我選擇的菜單選項設置，所需的活動打開完美，但是，當我試圖返回數據時，它導致一個力量關閉

爲什麼我遇到強制關閉嗎？

我真的很感激幫助這裏的問題

按照建議

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(); 
     }

'$資源NotFoundException：字符串資源ID＃爲0x1" ' – keyser

@Keyser感謝您的回覆。你能解釋一下嗎？我是新來的機器人，因此我在理解Logcat條目時遇到了一些困難。 – Anant

對不起，不能給你更多的東西，但這就是力量關閉的原因。查看所有的字符串資源代碼。 – keyser

如果你看到Toast.makeText

public static Toast makeText (Context context, int resId, int duration)

所以利息

謝謝如果你給第二參數作爲int然後系統會查找此ID在R.java但具有諷刺意味的是其實你想打印的數量，以便只投你的第二個參數String即this

public static Toast makeText (Context context, CharSequence text, int duration)

變化吐司行代碼

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

或

Toast.makeText(getBaseContext(),String.valueOf(requestCode), Toast.LENGTH_SHORT).show();

感謝您的回答。但是，我仍然得到相同的力量關閉錯誤 – Anant

它肯定會工作。 –

對不起，但不幸的是，它仍然給我一個力量關閉錯誤。根據您的建議，我編輯了我的問題以反映代碼。 – Anant

你應該使用，而不是URI mIntent.putExtra ... 檢查這個鱈魚Ë....

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); 
     } 

    } 

}`

Setting.java

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) { 

      EditText mind = (EditText) findViewById(R.id.minDistance); 
      Intent data = getIntent(); 
      data.putExtra("data", mind.getText().toString()); 
      Toast.makeText(getBaseContext(), mind.getText().toString(), Toast.LENGTH_SHORT).show(); 

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

    }); 

}

}
