今天閒的無聊,研究了下launcher代碼,看到Hotseat.java的時候,想起來以前有做過顯示hotseat中應用名稱,因爲換了公司代碼都沒拿出來,就想在試着修改,看了很久發現無從下手,記得hotseat中默認是顯示應用名稱的,只是hotseat位置靠下所以名稱顯示不出來,只要把hotseat向上移一下就可以顯示出來了,可是找了半天不知道修改那個位置,只能重新研究下hotseat的代碼了。
看hotseat.java中
@Override
protected void onFinishInflate() {
super.onFinishInflate();
LauncherAppState app = LauncherAppState.getInstance();
DeviceProfile grid = app.getDynamicGrid().getDeviceProfile();
mAllAppsButtonRank = grid.hotseatAllAppsRank;
mContent = (CellLayout) findViewById(R.id.layout);
if (grid.isLandscape && !grid.isLargeTablet()) {
mContent.setGridSize(1, (int) grid.numHotseatIcons);
} else {
mContent.setGridSize((int) grid.numHotseatIcons, 1);
}
mContent.setIsHotseat(true);
Log.i(TAG, "onFinishInflate,(int) grid.numHotseatIcons: " + (int) grid.numHotseatIcons);
resetLayout();
}
mContent.setIsHotseat(true); 這個是判斷是否是Hotseat的地方,簡便的做法是直接修改爲false,意思是這個這個不是HotSeat,那麼作爲普通快捷圖標肯定是能顯示名稱的,但是這有一個問題那個allapp的名稱還是沒顯示出來,暫時的做法是allAppsButton.setText(context.getString(R.string.all_apps_button_label));
這樣hotseat就可以正常顯示應用名稱了。
在cellLayout.java中
public void setIsHotseat(boolean isHotseat) {
mIsHotseat = isHotseat;
mShortcutsAndWidgets.setIsHotseat(false);}
public boolean addViewToCellLayout(View child, int index, int childId, LayoutParams params,
boolean markCells) {
final LayoutParams lp = params;
// Hotseat icons - remove text
if (child instanceof BubbleTextView) {
BubbleTextView bubbleChild = (BubbleTextView) child;
bubbleChild.setTextVisibility(!mIsHotseat);
}
...
}
發現 addview的時候會根據是否是HotSeat去顯示和隱藏,但是隻改這裏會發現字體只顯示了一半,繼續跟蹤mShortcutsAndWidgets.setIsHotseat(false);
終於明白了
public void setIsHotseat(boolean isHotseat) {
mIsHotseatLayout = isHotseat;
}
int getCellContentWidth() {
final LauncherAppState app = LauncherAppState.getInstance();
final DeviceProfile grid = app.getDynamicGrid().getDeviceProfile();
return Math.min(getMeasuredHeight(), mIsHotseatLayout ?
grid.hotseatCellWidthPx: grid.cellWidthPx);
}
int getCellContentHeight() {
final LauncherAppState app = LauncherAppState.getInstance();
final DeviceProfile grid = app.getDynamicGrid().getDeviceProfile();
return Math.min(getMeasuredHeight(), mIsHotseatLayout ?
grid.hotseatCellHeightPx : grid.cellHeightPx);
}
原來這裏會通過會通過判斷是否是HotSeat而去設置icon的寬高。到這裏Hotseat顯示名稱的分析就結束了。
