[Android] lithid-cm:
This is just going to be a quick rundown on what do to add new toggles to android new QuickSettings system. This will take place in SystemUI.

Custom QuickSettings Toggles

Path: frameworks/base/packages/SystemUI

Files:

src/com/android/systemui/statusbar/phone/QuickSettings.java

There are two options when creating a toggle.

addSystemTiles:380 - Static tiles with useful information.

addTemporaryTiles:571 - This type of tile will get removed without activity, for example, the alarm quick setting is a temp tile.

I used SystemTiles

// CpuInfo tile
QuickSettingsTileView cpuInfoTile = (QuickSettingsTileView)
inflater.inflate(R.layout.quick_settings_tile, parent, false);
cpuInfoTile.setContent(R.layout.quick_settings_tile_cpuinfo, inflater);
cpuInfoTile.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
startSettingsActivity(Intent.ACTION_POWER_USAGE_SUMMARY);
}
});
mModel.addCpuInfoTile(cpuInfoTile, new QuickSettingsModel.RefreshCallback() {
@Override
public void refreshView(QuickSettingsTileView view, State state) {
ImageView iv = (ImageView) view.findViewById(R.id.cpuinfo_image);
TextView tva = (TextView) view.findViewById(R.id.cpuinfoa_textview);
TextView tvb = (TextView) view.findViewById(R.id.cpuinfob_textview);
Drawable d = mContext.getResources().getDrawable(R.drawable.ic_settings_performance);
String GOV = fileReadOneLine(GOV_FILE);
String FREQ = fileReadOneLine(SCALE_CUR_FILE);
iv.setImageDrawable(d);
tva.setText(GOV);
tvb.setText(FREQ);
view.setContentDescription(
mContext.getString(R.string.accessibility_quick_settings_cpuinfo, GOV));
}
});
parent.addView(cpuInfoTile);

src/com/android/systemui/statusbar/phone/QuickSettingsModel.java:174

This is needed for the widget inside the toggle to get updated. You can view other definitions in here to update various states.

private QuickSettingsTileView mCpuInfoTile;
private RefreshCallback mCpuInfoCallback;
private State mCpuInfoState = new State();

res/layout/quick_settings_tile_cpuinfo.xml

This is where we create the layout of the tile and call it from java.

res/values/strings.xml

Needed to setContentDescription()

<string name="accessibility_quick_settings_cpuinfo">CpuInfo <xliff:g id="meminfo" example="CpuInfo">%s</xliff:g>.</string>

I know this is a very general overview, but the actuality is there is so much that can be done with this, it would be hard to go into extreme detail. Would be better to just simply leave that stuff for questions in this thread.

If you want to know more, please just ask. Lets make android OURS!​
