如何以编程方式获取每个应用程序的权限详情?
我想在 TextView 上显示 "每个应用程序的权限详情",但我尝试了却不行。请问怎样才能实现呢?
Hello.java
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ListView;
import android.content.Intent;
import android.content.Context;
import android.content.pm.*;
import android.widget.TextView;
import java.util.*;
public class HelloSakez extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
final ListView lw = (ListView) findViewById(R.id.listView1);
final List<ResolveInfo> pkglist = lw.getContext().getPackageManager().queryIntentActivities(mainIntent, 0);
final TextView tw = (TextView) findViewById(R.id.textView1);
Iterator it = pkglist.iterator();
while(it.hasNext()){
ResolveInfo rf = (ResolveInfo)it.next();
tw.append(rf.toString());
}
}
}
