我有一个包含一些动态内容的活动。

对于数组的每一项，都有不同的内容（textViews、复选框的数量……）用户单击“保存”按钮，然后屏幕必须自行刷新以显示下一项的内容。

我想知道像这样重新加载我的活动是否是一个好习惯：

Intent refresh = new Intent(this, conflictActivity.class);
startActivity(refresh)
finish()

而不是删除我的布局中的所有视图等......

我认为重新加载它更容易。还有另一种方法吗？

编辑：添加代码。

public class ConflicFieldTest extends Activity {

private int nbField;
private int nbChecked;


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

    final Button saveButton = (Button) findViewById(R.id.save);

    final LinearLayout leftLayout = (LinearLayout) findViewById(R.id.leftLayout);
    final LinearLayout rightLayout = (LinearLayout) findViewById(R.id.rightLayout);

    final TextView fieldName = new TextView(this);
    final LinearLayout editLayoutRight = new LinearLayout(this);
    final LinearLayout editLayoutLeft = new LinearLayout(this);

    final LinearLayout fieldRight = new LinearLayout(this);
    final LinearLayout fieldLeft = new LinearLayout(this);


    final ArrayList<String> allIdInConflict = getAllIdInConflict();
    for (int i = 0; i < allIdInConflict.size(); i++) {

        new AccountSyncTask() {

            @Override
            public void onPostExecute(
                    final ArrayList<ArrayList<String>> result) {

                nbField = 0;
                nbChecked = 0;



                final Map<String, Object> fieldsInConflict = conflict
                        .conflictWithFields(memoAccountMap,
                                serverAccountMap, modifiedAccountMap);


                for (Iterator<Map.Entry<String, Object>> field = fieldsInConflict
                        .entrySet().iterator(); field.hasNext();) {
                    final Map.Entry<String, Object> entry = field.next();

                    fieldName.setText(entry.getKey() + " : ");

                    final EditText[] editTextArrayRight = new EditText[fieldsInConflict

                    checkboxRight[nbField] = new CheckBox(
                            ConflicFieldTest.this);
                    checkboxLeft[nbField] = new CheckBox(

                                }
                            });

                    checkboxRight[i1]
                            .setOnClickListener(new OnClickListener() {

                    editLayoutLeft.addView(fieldName);

                                            LinearLayout.LayoutParams.WRAP_CONTENT));

                    editLayoutLeft
                            .addView(
                                    editTextArrayLeft[nbField],
                                    new LinearLayout.LayoutParams(

                    nbField++;

                }

                saveButton.setOnClickListener(new OnClickListener() {

                    @Override
                    public void onClick(View arg0) {
                        //save data & update UI
            }
        }

        .execute(appState.getSessionName(), id, "getObjectOnServer");

    }
}

对不起代码，它有点脏（我已经删除了一些部分），我正在修改它。

int flag = 0;
public void updateUI() {
  if(flag == 0) {
     //your normal codes...
  } else {
     //display view with user given data
  }
}

在 中调用此函数oncreate。首先标志将设置为零。当您在 textview 中输入数据并勾选复选框时，使用一些值更新标志。然后save Button单击再次调用此函数。现在标志已设置。因此它将显示更新的 UI。

我想这会给你一个想法..
