问题描述
我已修改解决方案.我能够获得进度条，但进度条永远不会隐藏
I have modify the solution. I am able to get the progress bar but the progress bar never gets hide
这里是创建具有相对布局的进度条的类
Here is class to create a progress bar with relative layout
public class ProgressBarHandler {
private ProgressBar mProgressBar;
private Context mContext;
private View _baseView;
private View _hideView;
public ProgressBarHandler(Context context,View baseView, View hideView) {
mContext = context;
_baseView = baseView;
_hideView = hideView;
ViewGroup layout = (ViewGroup) _baseView;//((Activity) context).findViewById(android.R.id.content).getRootView();
mProgressBar = new ProgressBar(context, null, android.R.attr.progressBarStyleLarge);
mProgressBar.setIndeterminate(true);
RelativeLayout.LayoutParams params = new
RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);
RelativeLayout rl = new RelativeLayout(context);
rl.setGravity(Gravity.CENTER);
rl.addView(mProgressBar);
layout.addView(rl, params);
hide();
}
public void show() {
mProgressBar.setVisibility(View.VISIBLE);
_hideView.setVisibility(View.INVISIBLE);
}
public void hide() {
mProgressBar.setVisibility(View.INVISIBLE);
_hideView.setVisibility(View.VISIBLE);
}
}
这是我的xml文件
<FrameLayout xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"
android:layout_height="match_parent"

<LinearLayout

android:layout_height="wrap_content"

android:orientation="vertical">

android:layout_gravity="center_horizontal"
android:text=""
android:layout_marginTop="5dp"
android:textColor="@color/white" />
</LinearLayout>
</RelativeLayout>
</LinearLayout>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v7.widget.RecyclerView
android:id="@+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
</android.support.v7.widget.RecyclerView>
</android.support.design.widget.CoordinatorLayout>
</FrameLayout>
这里是活动类，称为进度条
Here is the activity class which call the progress bar
public class ProfileActivity extends AppCompatActivity {
FrameLayout profile_root_layout;
CoordinatorLayout layot_to_hide;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_profile);
profile_root_layout = (FrameLayout) findViewById(R.id.profile_activity);
layot_to_hide = (CoordinatorLayout) findViewById(R.id.layout_to_hide);
new userProfileTask().execute();
}
public class userProfileTask extends AsyncTask<Void, Void, Boolean> {
@Override
protected void onPreExecute() {
new ProgressBarHandler(getBaseContext(),profile_root_layout,layot_to_hide).show();
super.onPreExecute();
}
@Override
protected Boolean doInBackground(Void... params) {
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(Boolean aBoolean) {
new ProgressBarHandler(getBaseContext(),profile_root_layout,layot_to_hide).hide();
}
}
}
进度条永远不会隐藏起来.我在哪里做错了.
The progress bar never gets hides.Where I am doing mistake.
推荐答案
制作一个单独的类，然后在其上创建一个带有参数的静态方法，该参数包含Activity ...在您的Activity上调用此方法，并在它
Make a separate class then make a static method with the parameter on it the parameter contain Activity ... call this method on ur activity and pass the Activity name in it
