                appNameAndPermissions.append("\n");
                }
                } catch (NameNotFoundException e) {
                e.printStackTrace();
                }
            }
        }
    });
}

activity_main.xml中

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.amazon.permissiondetector.MainActivity"
tools:ignore="MergeRootFrame" 
android:background="@color/black">

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="170dp"
    android:height="60dp"
    android:text="@string/buttontext"
    android:width="150dp" />

</RelativeLayout>

我是Android开发的新手，所以没有多少想法。创建应用程序以检测连接设备中所有应用程序使用的权限。就像插件探测器一样。我应该像App tile一样显示app.Guys使用的权限帮助我!!

提前致谢！

您需要在布局文件中添加TextView小部件。例如，您可以在按钮下方添加：

<TextView
android:id="@+id/txt_permissions"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>

然后在addListneronButton()末尾设置它的文字属性，如下所示：

txt_permissions.setText(appNameAndPermissions.toString())

如何将数据放入Android应用程序的文本视图模式。我可以将它放在日志中但不能将其置于文本视图模式
