Android学习笔记15

上次试了一般转圈圈的progressbar，这次换进度条的progressbarr
首先是xml

<ProgressBar
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    style="?android:attr/progressBarStyleHorizontal"
    android:layout_gravity="center"
    android:id="@+id/progressBar2"/>

其他跟上一篇一样即可，那我一样试做在dialogfragment里面kotlin如下

class FragmentDialog: DialogFragment() {
    
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
    }

    override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
        val view: View = inflater.inflate(R.layout.dialogfragment , container , false)
        val accountEditView = view.findViewById<EditText>(R.id.account)
        val passwordEditView = view.findViewById<EditText>(R.id.password)
        val loginButton = view.findViewById<Button>(R.id.login)
        val cancelButton = view.findViewById<Button>(R.id.cancel)
        val progressBar = view.findViewById<ProgressBar>(R.id.progressBar)
        val pgBar = view.findViewById<ProgressBar>(R.id.progressBar2)
        progressBar.visibility = View.VISIBLE
        pgBar.max = 100
        Thread{
            for (i in 0..100){
                pgBar.progress = i
                //Thread.sleep(500)
                SystemClock.sleep(500)
            }
        }.start()
        pgBar.progress = 0
        return view
    }
}

成果如下
