java如何从安卓中的另一个应用程序定义应用程序的屏幕方向？

Question

我有一个应用程序，我可以从中获得所有已安装应用程序及其图标的列表。这是我的密码：

package com.powergroupbd.appfilter;

import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.Iterator;
import java.util.List;

import 安卓.app.Activity;
import 安卓.content.pm.PackageInfo;
import 安卓.content.pm.PackageManager;
import 安卓.graphics.drawable.Drawable;
import 安卓.os.Bundle;
import 安卓.util.Log;
import 安卓.widget.ArrayAdapter;
import 安卓.widget.ListView;

public class ApplicationFilterActivity extends Activity {
    /** Called when the activity is first created. */

    ListView appfilter;
    // ArrayAdapter<Applications> adapter;
    PackageManager pck;
     ArrayList<Applications> results = new ArrayList<Applications>();


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

        appfilter = (ListView) findViewById(R.id.lvApp);

        PackageManager packageManager = this.getPackageManager();
        List<PackageInfo> applist = packageManager.getInstalledPackages(0);
        Iterator<PackageInfo> it = applist.iterator();
        while (it.hasNext()) {
            PackageInfo pk = (PackageInfo) it.next();
results.add(new Applications(pk.applicationInfo.loadIcon(packageManager), ""+pk.applicationInfo.loadLabel(packageManager)));
            Log.i("AppName", ""+pk.applicationInfo.loadLabel(packageManager));
}

         Collections.sort(results, new Comparator<Applications>() {
         @Override
         public int compare(Applications c1, Applications c2) {
         return c1.getAppname().compareToIgnoreCase(c2.getAppname());
         }
         });

        appfilter.setAdapter(new Customarrayadapter(this, results));
    }
}

但现在我想，如果我点击一个列表项，那么从下次开始，那个特定的应用程序将以横向方向打开，我需要知道如何才能做到这一点

Answer 1

我个人的经验是你想做的是不可能的。无法从其他应用程序强制应用程序仅以横向模式显示。如果我理解正确，您希望在横向模式下打开所选应用程序，即使设备处于纵向模式，对吗
