Question

我们通过从共享首选项中获取值来创建列表视图。工作流程将是这样的。

客户登录应用程序并点击“收藏夹”标签。对于第一次，将出现带有切换开关的模态视图。
客户可以选择切换开关以添加他们喜欢的选项并保存。
在下次登录时，当客户点击“收藏夹”标签时，该列表将显示其之前选择的选项。
现在我们要在按钮处添加一个静态按钮（用于编辑），点击该按钮将显示带有切换开关页面的模态视图。

但是当我尝试在我的XML文件中添加按钮时，我会在每一行中获得按钮。你在这方面的帮助将非常明显。

创建一个xml文件 dummy.xml 将以下代码粘贴到该文件中：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">

<ListView
    android:id="@+id/mylist"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1"/>

<Button
    android:id="@+id/btn_static"
    android:layout_gravity="center"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="STATIC"/>
</LinearLayout>

更改 dummy.java ，如下所示：

import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.preference.PreferenceManager;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ListView;
import android.widget.Toast;
import java.util.ArrayList;

import kvbank.kvb_epassbook.util.MobileArrayAdapter;

public class dummy extends Activity {
//String[] MOBILE_OS = new String[15] ;
ArrayList<String> MOBILE_OS = new ArrayList<String>();
Button btn_static;
ListView mylist;
MobileArrayAdapter adapter;

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.dummy);

    mylist = (ListView)findViewById(R.id.mylist);

    //This is your Button use it any where you want..!!

    btn_static = (Button)findViewById(R.id.btn_static);

    final SharedPreferences sp = PreferenceManager
            .getDefaultSharedPreferences(this);

    int count1 = sp.getInt("count", -1);
    String cc = String.valueOf(count1);
    System.out.println(cc);

    if ((count1 == 0) || (count1 == -1)) {
        Intent i = new Intent(this, favorites.class);
        startActivity(i);

        Toast.makeText(getApplicationContext(), "No favorites Set!!! =)",
                Toast.LENGTH_LONG).show();
    } else {


        SharedPreferences.Editor editor = sp.edit();

        boolean ad = sp.getBoolean("accdet", false);
        if (ad == true) {
            MOBILE_OS.add("AccountDetails");
        }
        boolean as = sp.getBoolean("accsumm", false);
        if (as == true) {
            MOBILE_OS.add("AccountSummary");
        }
        boolean ast = sp.getBoolean("accstmt", false);
        if (ast == true) {
            MOBILE_OS.add("AccountStatement");
        }
        boolean crl = sp.getBoolean("CRL", false);
        if (crl == true) {
            MOBILE_OS.add("Cash Remitance Limit");
        }
        boolean cse = sp.getBoolean("CSE", false);
        if (cse == true) {
            MOBILE_OS.add("Cheque Status Enquiry");
        }
        boolean ic = sp.getBoolean("inwchq", false);
        if (ic == true) {
            MOBILE_OS.add("Inward Cheque");
        }
        boolean uca = sp.getBoolean("Unclramt", false);
        if (uca == true) {
            MOBILE_OS.add("uncleared Amount");
        }
        boolean dt = sp.getBoolean("depdet", false);
        if (dt == true) {
            MOBILE_OS.add("Deposit Details");
        }

        adapter = new MobileArrayAdapter(this, MOBILE_OS);

        mylist.setAdapter(adapter);

        mylist.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
            @Override
            public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {

                String selectedValue = (String) adapter.getItem(position);
                Toast.makeText(dummy.this, selectedValue, Toast.LENGTH_SHORT).show();

                return false;

            }
        });

    }

}
}
