Question

 submitButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent intent = new Intent();

            if(companyNameEditText.getText().toString()!=null) {
                intent.putExtra("companyName", companyNameEditText.getText().toString());
                 nameChanged=true;
                finish();
            }
            else{
                Toast.makeText(ChangeNameActivity.this,"Please enter a value",Toast.LENGTH_SHORT).show();
            }
        }
    });

 @Override
protected void onDestroy() {
    super.onDestroy();
    if(nameChanged)
    {
        activityFinishedWithChanges= true;
    }
}

 @Override
protected void onResume() {
    super.onResume();
    if(ChangeNameActivity.activityFinishedWithChanges) {
        companyNameText = findViewById(R.id.companyNameText);
        if (getIntent().hasExtra("companyName")) {
            String companyName = getIntent().getStringExtra("companyName");
            if (companyName != null) {
                if (!companyName.equals("")) {
                    companyNameText.setText(companyName);
                    AppUtils.setNameSharedPreference(BrandSettingsActivity.this, AppConstants.organizationName, getIntent().getStringExtra("companyName"));
                }
            }
        }
    }
}

如果我正确地理解了您的问题，您希望将数据从（第二个活动）发送到您的periverivered opened（第一个活动）

因此，从FirstActivity使用startActivityForResult（）方法调用SecondActivity

例如：

int ACTIVITY_CODE= 1
Intent i = new Intent(this, SecondActivity.class);
startActivityForResult(i, ACTIVITY_CODE);

Intent returnIntent = new Intent();
returnIntent.putExtra("result",result);
setResult(Activity.RESULT_OK,returnIntent);
finish();

@Override
protected void onActivityResult(int requestCode, int     resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);

if (requestCode == ACTIVITY_CODE) {
    if(resultCode == Activity.RESULT_OK){
        String result=data.getStringExtra("result");
    }
    if (resultCode == Activity.RESULT_CANCELED) {
        //Write your code if there's no result
    }
  }
}
