修改前 修改后 二、找到对应类
通过aidegen 打断点调试对应代码类VolumeDialogImpl定位到volume_dialog就是对话框布局。mDialog.setContentView(R.layout.volume_dialog);
类路径frameworks/base/packages/SystemUI/src/com/android/systemui/volume/VolumeDialogImpl.java
private void initDialog() {mDialog new CustomDialog(mContext);initDimens();mConfigurableTexts new ConfigurableTexts(mContext);mHovering false;mShowing false;mWindow mDialog.getWindow();mWindow.requestFeature(Window.FEATURE_NO_TITLE);mWindow.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));mWindow.clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND| WindowManager.LayoutParams.FLAG_LAYOUT_INSET_DECOR);mWindow.addFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE| WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL| WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED| WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH| WindowManager.LayoutParams.FLAG_HARDWARE_ACCELERATED);mWindow.addPrivateFlags(WindowManager.LayoutParams.PRIVATE_FLAG_TRUSTED_OVERLAY);mWindow.setType(WindowManager.LayoutParams.TYPE_VOLUME_OVERLAY);mWindow.setWindowAnimations(com.android.internal.R.style.Animation_Toast);WindowManager.LayoutParams lp mWindow.getAttributes();lp.format PixelFormat.TRANSLUCENT;lp.setTitle(VolumeDialogImpl.class.getSimpleName());lp.windowAnimations -1;lp.gravity mContext.getResources().getInteger(R.integer.volume_dialog_gravity);mWindow.setAttributes(lp);mWindow.setLayout(WRAP_CONTENT, WRAP_CONTENT);mDialog.setContentView(R.layout.volume_dialog);mDialogView mDialog.findViewById(R.id.volume_dialog);mDialogView.setAlpha(0);mDialog.setCanceledOnTouchOutside(true);
三、音量条代码 SuppressLint(InflateParams)private void initRow(final VolumeRow row, final int stream, int iconRes, int iconMuteRes,boolean important, boolean defaultStream) {row.stream stream;row.iconRes iconRes;row.iconMuteRes iconMuteRes;row.important important;row.defaultStream defaultStream;row.view mDialog.getLayoutInflater().inflate(R.layout.volume_dialog_row, null);row.view.setId(row.stream);row.view.setTag(row);row.header row.view.findViewById(R.id.volume_row_header);row.header.setId(20 * row.stream);if (stream STREAM_ACCESSIBILITY) {row.header.setFilters(new InputFilter[] {new InputFilter.LengthFilter(13)});}row.dndIcon row.view.findViewById(R.id.dnd_icon);row.slider row.view.findViewById(R.id.volume_row_slider);row.slider.setOnSeekBarChangeListener(new VolumeSeekBarChangeListener(row));row.number row.view.findViewById(R.id.volume_number);row.anim null;final LayerDrawable seekbarDrawable (LayerDrawable) mContext.getDrawable(R.drawable.volume_row_seekbar);final LayerDrawable seekbarProgressDrawable (LayerDrawable)((RoundedCornerProgressDrawable) seekbarDrawable.findDrawableByLayerId(android.R.id.progress)).getDrawable();row.sliderProgressSolid seekbarProgressDrawable.findDrawableByLayerId(R.id.volume_seekbar_progress_solid);final Drawable sliderProgressIcon seekbarProgressDrawable.findDrawableByLayerId(R.id.volume_seekbar_progress_icon);row.sliderProgressIcon sliderProgressIcon ! null ? (AlphaTintDrawableWrapper)((RotateDrawable) sliderProgressIcon).getDrawable() : null;row.slider.setProgressDrawable(seekbarDrawable);row.icon row.view.findViewById(R.id.volume_row_icon);row.setIcon(iconRes, mContext.getTheme());if (row.icon ! null) {if (row.stream ! AudioSystem.STREAM_ACCESSIBILITY) {row.icon.setOnClickListener(v - {Events.writeEvent(Events.EVENT_ICON_CLICK, row.stream, row.iconState);mController.setActiveStream(row.stream);if (row.stream AudioManager.STREAM_RING) {final boolean hasVibrator mController.hasVibrator();if (mState.ringerModeInternal AudioManager.RINGER_MODE_NORMAL) {if (hasVibrator) {mController.setRingerMode(AudioManager.RINGER_MODE_VIBRATE, false);} else {final boolean wasZero row.ss.level 0;mController.setStreamVolume(stream,wasZero ? row.lastAudibleLevel : 0);}} else {mController.setRingerMode(AudioManager.RINGER_MODE_NORMAL, false);if (row.ss.level 0) {mController.setStreamVolume(stream, 1);}}} else {final boolean vmute row.ss.level row.ss.levelMin;mController.setStreamVolume(stream,vmute ? row.lastAudibleLevel : row.ss.levelMin);}row.userAttempt 0; // reset the grace period, slider updates immediately});} else {row.icon.setImportantForAccessibility(View.IMPORTANT_FOR_ACCESSIBILITY_NO);}}}四、音量条布局则位于volume_dialog_row.xml中
