これが私のコードのセクションです:
@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);
}
}
}
これがSettings.javaのコードです
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();*/
}
});
}
}
これで、 [設定]のメニューオプションを選択すると、必要なアクティビティが完全に開きますが、データを返そうとすると、強制的に閉じられます

提案に従って
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();
}
