It's almost 4rth day i'm trying to make my own customize mediacontroller. But fail. What i did is Create MyMediaController class and extend MediaController and override all of it's method.
Original MediaController setAnchorView code.
public void setAnchorView(View view) {
if (mAnchor != null) {
mAnchor.removeOnLayoutChangeListener(mLayoutChangeListener);
}
mAnchor = view;
if (mAnchor != null) {
mAnchor.addOnLayoutChangeListener(mLayoutChangeListener);
}
FrameLayout.LayoutParams frameParams = new FrameLayout.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT
);
removeAllViews();
View v = makeControllerView();
addView(v, frameParams);
}
MyMediaController setAnchorView code.
@Override
public void setAnchorView(View view) {
mAnchor = view;
FrameLayout.LayoutParams frameParams = new FrameLayout.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT
);
removeAllViews();
View v = makeControllerView();
addView(v, frameParams);
}
Another difference is in show method.
Original show method.
public void show(int timeout) {
if (!mShowing && mAnchor != null) {
setProgress();
if (mPauseButton != null) {
mPauseButton.requestFocus();
}
disableUnsupportedButtons();
updateFloatingWindowLayout();
mWindowManager.addView(mDecor, mDecorLayoutParams);
mShowing = true;
}
updatePausePlay();
// cause the progress bar to be updated even if mShowing
// was already true. This happens, for example, if we're
// paused with the progress bar showing the user hits play.
post(mShowProgress);
if (timeout != 0 && !mAccessibilityManager.isTouchExplorationEnabled()) {
removeCallbacks(mFadeOut);
postDelayed(mFadeOut, timeout);
}
}
My show code.
@Override
public void show(int timeout) {
if (!mShowing && mAnchor != null) {
setProgress();
if (mPauseButton != null) {
mPauseButton.requestFocus();
}
FrameLayout.LayoutParams tlp = new FrameLayout.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT,
Gravity.BOTTOM
);
addView(this, tlp);
mShowing = true;
}
updatePausePlay();
// cause the progress bar to be updated even if mShowing
// was already true. This happens, for example, if we're
// paused with the progress bar showing the user hits play.
post(mShowProgress);
if (timeout != 0 && !mAccessibilityManager.isTouchExplorationEnabled()) {
removeCallbacks(mFadeOut);
postDelayed(mFadeOut, timeout);
}
}
When addView(this,tlp) method in my show method call. It give error.
E/InputEventReceiver: Exception dispatching input event.
E/MessageQueue-JNI: Exception in MessageQueue callback: handleReceiveCallback
E/MessageQueue-JNI: java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

When i change View mAnchor variable to ViewGroup mAnchor and then change show method to following and use it with surfaceView then it works. But i want to use it with VideoView so i can't make View mAnchor to ViewGroup mAnchor.
public void show(int timeout) {
if (!mShowing && mAnchor != null) {
setProgress();
if (mPauseButton != null) {
mPauseButton.requestFocus();
}
FrameLayout.LayoutParams tlp = new FrameLayout.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT,
Gravity.BOTTOM
);
mAnchor.addView(this, tlp);
mShowing = true;
}
updatePausePlay();
// cause the progress bar to be updated even if mShowing
// was already true. This happens, for example, if we're
// paused with the progress bar showing the user hits play.
post(mShowProgress);
if (timeout != 0 && !mAccessibilityManager.isTouchExplorationEnabled()) {
removeCallbacks(mFadeOut);
postDelayed(mFadeOut, timeout);
}
}
I know it should give error. But didn't know how to resolve it. If someone think i did it wrong plz give me suggestion, how i should do it. I didn't want to use customize mediacontroller with surfaceView. I want to use it with VideoView. I really need help.
