我有一个单独布局的进度条,我想在singletonclass中进行progressbar实现,并在所有frament中使用singleton类的方法。我该怎么做。
这是我的progressbar.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="65dp"
android:background="#43A6F3"
android:orientation="vertical">
<TextView
android:id="@+id/progress_text"
android:layout_width="wrap_content"
android:layout_height="40dp"
android:layout_above="@+id/progress_bar"
android:layout_marginLeft="10dp"
android:layout_marginStart="10dp"
android:background="@android:color/transparent"
android:gravity="center_vertical"
android:text=""
android:textColor="@android:color/white"
android:textSize="16sp"
android:visibility="gone" />
<ProgressBar
android:id="@+id/progress_bar"
style="@android:style/Widget.DeviceDefault.Light.ProgressBar.Horizontal"
android:layout_width="match_parent"
android:layout_height="30dp"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_gravity="center"
android:background="#FFFF"
android:maxHeight="20dp"
android:minHeight="20dp" />
这是我的单身人士课程
public class CShowProgress {
public static CShowProgress s_m_oCShowProgress;
public static Context m_Context;
public Dialog m_Dialog;
public ProgressBar m_ProgressBar;
public CShowProgress(Context m_Context) {
this.m_Context = m_Context;
}
public static CShowProgress getInstance() {
if (s_m_oCShowProgress == null) {
s_m_oCShowProgress = new CShowProgress(m_Context);
}
return s_m_oCShowProgress;
}
public void showProgress(String message) {
m_Dialog = new Dialog(m_Context);
m_Dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
m_Dialog.setContentView(R.layout.progress_bar);
m_ProgressBar = (ProgressBar) m_Dialog.findViewById(R.id.progress_bar);
TextView progressText = (TextView) m_Dialog.findViewById(R.id.progress_text);
progressText.setText("" + message);
progressText.setVisibility(View.VISIBLE);
m_ProgressBar.setVisibility(View.VISIBLE);
m_ProgressBar.setIndeterminate(true);
m_Dialog.setCancelable(false);
m_Dialog.setCanceledOnTouchOutside(false);
m_Dialog.show();
}
这是我的片段/活动,我必须使用showProgress()
protected void onPreExecute() {
super.onPreExecute();
CShowProgress.getInstance.showProgress("Please wait while Loading Deals...");
}

public class CShowProgress {
public static CShowProgress s_m_oCShowProgress;
public Dialog m_Dialog;
private ProgressBar m_ProgressBar;
private Context context;
private CShowProgress(Context context) {
this.context = context;
}
public static CShowProgress getInstance() {
if (s_m_oCShowProgress == null) {
s_m_oCShowProgress = new CShowProgress(m_Context);
}
return s_m_oCShowProgress;
}
public void showProgress(Context m_Context,String message) {
m_Dialog = new Dialog(m_Context);
m_Dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
m_Dialog.setContentView(R.layout.progress_bar);
m_ProgressBar = (ProgressBar) m_Dialog.findViewById(R.id.progress_bar);
TextView progressText = (TextView) m_Dialog.findViewById(R.id.progress_text);
progressText.setText("" + message);
progressText.setVisibility(View.VISIBLE);
m_ProgressBar.setVisibility(View.VISIBLE);
m_ProgressBar.setIndeterminate(true);
m_Dialog.setCancelable(false);
m_Dialog.setCanceledOnTouchOutside(false);
m_Dialog.show();
}
use it like this in fragments
CShowProgress progressbar = CShowProgress.getInstance();
progressbar.showProgress(getActivity(),"Your message")
